Rescue teams were combing the Potomac River after a plane carrying 64 people and a U.S. Army Blackhawk helicopter collied near Ronald Reagan National Airport in Arlington, Virginia, on Wednesday night.

The big picture: Both the American Airlines regional jet that was flying from Wichita, Kansas, to D.C. and the helicopter was carrying three people while on a training exercise were in the river, officials said.

An American Airlines regional passenger jet carrying 64 people collided with a U.S. Army Black Hawk helicopter in midair near Ronald Reagan Washington National Airport in Arlington, Virginia, on Wednesday night, officials said, citing preliminary reports.

The latest: Emergency respondents were now "switching from a rescue operation to a recovery operation," D.C. Fire and EMS Department chief John Donnelly said at a press briefing Thursday morning.

• "At this point, we don't believe there are any survivors from this accident, and we have recovered 27 people from the plane and one from the helicopter," Donnelly added.
• Remnants of the two aircrafts have been discovered, including the fuselage of the American Airlines plane, which was found in three sections, Secretary of Transportation Sean Duffy said at a press briefing Thursday morning.

State of play: Duffy added that the U.S. still "absolutely" had the safest airspace in the world.

• The cause of the crash is still under investigation. "Something went wrong here," Duffy acknowledged, though he stressed that both aircrafts' flight paths in the lead up to the collision were standard for the D.C. airspace and that there hadn't been a communication breakdown.
• A little over 14 hours after the collision, the airport can "safely" reopen at 11am, said Jack Potter, head of the Metropolitan Washington Airports Authority.

The big picture: The American Eagle Flight 5342 was en route from Wichita, Kansas, to Washington, D.C., with 60 passengers and four crew members on board, per a statement on American Airlines' website about the incident involving its subsidiary airline.

• Defense Secretary Pete Hegseth shared a statement on X just after midnight Thursday from a Defense Department spokesperson saying the U.S. Army UH-60 helicopter was on a training exercise out of Fort Belvoir, Virginia, when the incident happened.

Zoom in: The collision prompted a ground stop and Reagan Washington National Airport said on X all takeoffs and landings had been "halted at DCA."

• A figure skating group said on X that skaters, coaches and their families were on the flight following the U.S. Figure Skating Championships in Wichita. Kremlin spokesperson Dmitry Peskov confirmed on Telegram that Russian figure skaters and other citizens were on board.

What they're saying: President Trump thanked first responders in an emailed statement late Wednesday and said that he'd been "fully briefed on the terrible accident," adding: "May God Bless their souls."

• Trump made clear on Truth Social early Thursday that he's seeking answers on how the collision happened, saying: "This is a bad situation that looks like it should have been prevented."

What we're watching: Donnelly said at an early Thursday morning briefing some 300 responders were at the scene, where temperatures were expected to be below freezing overnight.

• Homeland Security Secretary Kristi Noem said on X her department was "deploying every available" U.S. Coast Guard resource for search and rescue efforts.
• The Federal Aviation Administration said it would investigate the incident alongside the National Transportation Safety Board, with the latter leading the probe.

Background: Reagan Washington National Airport is owned by the federal government and operated by the Metropolitan Washington Airports Authority, which serves the D.C. metropolitan area.

• It's an American Airlines hub that provides nonstop flights to 102 domestic destinations and six international destinations, per the airport's website.

Flashback: Wednesday's collision is the worst air tragedy in the D.C. area since the Air Florida Flight 90 crash on Jan. 13, 1982.

• The plane crashed into the 14th Street Bridge after take off from Reagan Washington National Airport, killing 70 passengers, four crew members and four people in vehicles on the bridge over the Potomac River.

Defense Secretary Pete Hegseth is revoking Gen. Mark Milley's personal security detail and clearance — and the former Joint Chiefs of Staff chair faces a review that could result in a rank demotion, the Pentagon announced Tuesday night.

Why it matters: President Trump has since being sworn in last week moved to target those he regards as "the enemies from within" — among them Milley, for whom President Biden issued a preemptive pardon before leaving office, per Axios' Zachary Basu.

Details: Pentagon spokesperson John Ullyot said in an emailed statement that Hegseth relayed the action earlier Tuesday to Milley, who served as the top U.S. Army general under Biden and in the first Trump administration from 2019 to 2023.

• Hegseth also directed the Defense Department inspector general "to conduct an inquiry into the facts and circumstances surrounding Gen. Milley's conduct so that the Secretary may determine whether it is appropriate to reopen his military grade review determination," Ullyot added.

What they're saying: Defense Department chief of staff Joe Kasper –said in the Pentagon email: "Undermining the chain of command is corrosive to our national security, and restoring accountability is a priority for the Defense Department under President Trump's leadership."

The big picture: Trump announced in 2018 he would nominate Milley to be the top U.S. general.

• However, their relationship deteriorated toward the end of his first term — notably after Milley publicly apologized for accompanying Trump to a photo op at St. John's Church in D.C. during protests linked to the murder of George Floyd.

Flashback: Trump once suggested Milley should be executed for treason after The Atlantic reported he communicated with his Chinese counterpart in the wake of the Jan. 6 Capitol riot.

• Meanwhile, Milley told journalist Bob Woodward during an interview for his book, "War," that Trump is "fascist to the core."
• He told military members at a 2023 ceremony marking his retirement: "Don't take an oath to a wannabe dictator."
• Biden noted in his statement on pardoning Milley that the general had been "threatened with criminal prosecutions."

Flash forward: The Pentagon removed a portrait of Milley and Trump publicly fired the general and thousands of other Biden presidential council appointees soon after the president took office.

Axios Future of Defense reporter Colin Demarest contributed reporting.

ICE announced Monday a multi-agency immigration clampdown resulted in 1,179 arrests in a single day — the biggest number since President Trump took office a week ago.

Why it matters: The Trump administration is stepping up efforts targeting undocumented immigrants in cities across the U.S. — and it's resulted in at least 3,552 arrests since Thursday, per figures posted to Immigration and Customs Enforcement's X account.

• Under the Biden administration, the average number of arrests of noncitizens with criminal convictions or pending charges in the fiscal year that ended Sept. 30 was 310.7 per day, according to an ICE report.

By the numbers: ICE on Thursday reported 538 arrests, on Friday the number announced was 593, on Saturday it was 286, on Sunday it was 956 and on Monday it was 1,179.

The big picture: Trump moved to unleash sweeping limits on immigration and asylum soon after taking office last Monday, declaring a national emergency on the U.S.-Mexico border and signing a flurry of executive orders.

• In the Republican-controlled Congress, lawmakers are pushing tough immigration bills — with the House last week passing and sending to Trump's desk the Laken Riley Act, which would require the detention of undocumented immigrants arrested for some crimes.

Meanwhile, House Oversight and Government Reform Committee Chair James Comer (R-Ky.) announced Monday that sanctuary cities Boston, Denver, Chicago and New York City were under investigation for "their impact on public safety and federal immigration enforcement."

President Trump's "border czar" Tom Homan and other top officials oversaw immigration enforcement efforts in Chicago on Sunday, as ICE officials announced Sunday 956 arrests in one day.

The latest: ICE has made over 3,500 arrests during Trump's first week back in office.

Why it matters: The massive arrests announced by Immigration and Customs Enforcement under Trump since he took office last Monday and declared a national emergency on the U.S.-Mexico border is a clear sign that his administration is stepping up efforts to crack down on undocumented immigrants.

• By comparison, an ICE report shows the average number of daily arrests of noncitizens with criminal convictions or pending charges in the fiscal year that ended Sept. 30 was 310.7.

State of play: "U.S. Immigration and Customs Enforcement, along with federal partners, including the FBI, ATF, DEA, CBP and the U.S. Marshals Service, began conducting enhanced targeted operations today in Chicago," per a post to ICE's website Sunday.

• The goal is "to enforce U.S. immigration law and preserve public safety and national security by keeping potentially dangerous criminal aliens out of our communities."
• The DEA Chicago was assisting the Department of Human Services "and other federal law enforcement partners with their immigration enforcement efforts," per a post to X that featured images of Homan and acting Deputy Attorney General Emil Bove.

What they're saying: Homan told ABC's "This Week" earlier Sunday that arrest and deportation numbers would "steadily increase," adding: "Right now, it's concentrating on public safety threats, national security threats. That's a smaller population."

• Chicago Mayor Brandon Johnson (D) said on X the city's police were "not involved" in federal enforcement efforts and emphasized that Chicagoans should "know their constitutional rights."

Zoom out: Hours after being sworn in as president for a second time, Trump signed executive orders to rework U.S. immigration policy.

• These include sending sending troops to the southern border and permitting immigration raids on churches and schools to arrest undocumented immigrants.
• Trump's executive order on ending birthright citizenship for those born to undocumented immigrants is being challenged in lawsuits by civil rights groups and Democratic state attorneys general, who contend that it conflicts with the 14th Amendment.

Go deeper: Trump pausing Colombia tariffs after migrants deal, White House says

Editor's note: This article has been updated with new details throughout.

President Trump won't impose tariffs on Colombia after the government agreed to accept all of his terms — including receiving Colombians deported from the U.S., White House press secretary Karoline Leavitt announced Sunday night.

Why it matters: It's a dramatic turnaround given Colombian President Gustavo Petro announced retaliatory tariffs hours after Trump said earlier Sunday he'd impose 25% tariffs on all goods imported from Colombia, which is a leading supplier of coffee and flowers in the U.S.

The latest: Colombian Foreign Minister Luis Gilberto Murillo said in a statement late Sunday the country's government had "overcome the impasse" with the U.S. and the nation's presidential plane was "ready to facilitate the return of Colombians who were going to arrive in the country this morning on deportation flights."

What they're saying: "The Government of Colombia has agreed to all of President Trump's terms, including the unrestricted acceptance of all illegal aliens from Colombia returned from the United States, including on U.S. military aircraft, without limitation or delay," Leavitt said in a statement.

• "Based on this agreement, the fully drafted IEEPA tariffs and sanctions will be held in reserve, and not signed, unless Colombia fails to honor this agreement," she said.

Yes, but: Leavitt said the State Department-issued visa sanctions and "enhanced inspections from Customs and Border Protection" will "remain in effect until the first planeload of Colombian deportees is successfully returned."

The intrigue: Petro initially reposted the White House statement announcing Trump's decision that Leavitt posted to X, but appears to have since rescinded this action.

State of play: Trump said on Truth Social early Sunday he would target Colombia with other sanctions in addition to the tariffs imposed over the refusal to accept flights — including a travel ban on government officials and financial penalties.

• Petro had ordered Colombian officials to turn away U.S. military planes carrying deportees, but later said he had arranged for his presidential plane to help repatriate Colombians.
• Trump's threat to impose tariffs and other sanctions on Colombia after the Latin American country refused to accept two deportation flights from the U.S. briefly ignited fears of a further surge in already high coffee prices, Axios' Ben Berkowitz notes.

What we're watching: Murillo and other top Colombian officials will travel to Washington, D.C., in the coming days for high-level meetings to follow up on the agreements, per the foreign minister's statement.

Background: Colombia has remained a key U.S. ally under the tenure of leftist leader Petro, per Axios' Astrid Galván and Avery Lotz.

• "Colombia is also the United States' third-largest trade partner in Latin America and U.S.-owned affiliates account for more than 90,000 jobs in Colombia," according to the State Department.
• The U.S. is the largest trade and investment partner of Colombia, with more than $39.3 billion in goods and services traded in 2022 amid "large investments" in the mining and manufacturing sectors, per the State Department.

South Korea's impeached President Yoon Suk Yeol was indicted on insurrection charges on Sunday after he briefly declared martial law last month, prosecutors told local media.

Why it matters: Yoon is the first sitting president to both be arrested and indicted on criminal charges.

• He could face life in prison or even the death penalty if convicted of insurrection because presidential immunity doesn't extend to such an offense in South Korea.

The big picture: Yoon denies any wrongdoing over his emergency martial law declaration, which sparked widespread protests and shocked allied nations before he rescinded it hours later.

• Former Defense Minister Kim Yong-hyun and other top officials are also facing insurrection charges over Yoon's declaration that the president claimed was to counter "pro-North Korean" elements in the country.
• Yoon was impeached and suspended from presidential duties over his actions and has been in detention since his Jan. 15 arrest following an hours-long standoff between law enforcement and the president's guard and supporters.

What they're saying: "[The] President's declaration of emergency martial law was a desperate plea to the public over a national crisis caused by the opposition getting out of control," Yoon's lawyers said in a statement, per Reuters.

President Trump bragged about overturning Roe v. Wade in a video address to tens of thousands of attendees at the March for Life anti-abortion rally in Washington, D.C., on Friday.

The big picture: Trump had shied away from abortion while campaigning after it became a winning issue for Democrats. His speech Friday found him once again leaning into a core priority for many Republicans.

• The annual March for Life comes one day after Trump pardoned 23 anti-abortion activists who were convicted of illegally blockading a reproductive health clinic in D.C.

Driving the news: In a recorded video address, Trump called Roe v. Wade an "unconstitutional decision" that kicked off "50 years of division and anger."

• He vowed to "stop the radical Democrat push for a federal right to unlimited abortion-on-demand, up to the moment of birth and even after birth," repeating a false claim he's made in the past.
• After flip-flopping on a national ban, Trump vowed on the campaign trail to leave abortion to individual states. Vice President JD Vance previously expressed support for a national ban, and Trump once called a national ban after 15 weeks "very reasonable."
• "In my second term, we will again stand proudly for families and for life," Trump said.

Vance, attending in person, touted the "return of the most pro-family, most pro-life American president of our lifetime."

• He said it's the task of the government to make it easier to afford having children.
• "We need a culture that celebrates life at all stages, one that recognizes and truly believes that the benchmark of national success is not our GDP number or our stock market, but whether people feel that they can raise thriving and healthy families in our country," the VP added.

Zoom out: Florida Gov. Ron DeSantis also addressed the rally Friday afternoon, and told the crowd: "Since we were able to beat Amendment Four, Florida's not only the place where woke goes to die, it's the place where babies go to live."

• House Speaker Mike Johnson (R-La.) and Senate Majority Leader John Thune (R-S.D.) gave remarks earlier too.

What they're saying: "President Trump governed as a pro-life president during his first term, which resulted in a long list of accomplishments," March for Life leaders Jeanne Mancini and Jennie Bradley said in a statement Thursday.

• "We look forward to working with him and Vice President Vance as they dismantle the Biden Administration's aggressive and unpopular abortion agenda and once again put wins on the board for vulnerable unborn children and their mothers."

What we're watching: Anti-abortion groups see limiting access to mifepristone as a top priority in Trump's term, but the president in a December Time magazine interview committed to protecting access to the abortion pill.

Flashback: Trump in 2020 became the first sitting president to attend the March for Life rally in person.

Editor's note: This is a developing story. Check back for updates.

President Trump signed pardons on Thursday for 23 anti-abortion protesters who were convicted of illegally blockading a reproductive health clinic in Washington, D.C.

What they're saying: "They should not have been prosecuted; it's a great honor to sign this," Trump said as he signed the order one day before he's due to speak via video at anti-abortion activists' annual March for Life rally on the National Mall in D.C., which Vice President JD Vance is due to address in person.

• After White House staff secretary Will Scharf told Trump the pardons were for "peaceful pro-life protesters who were prosecuted by the Biden administration," Trump said "many" of the activists were "elderly people."
• Trump described it as "ridiculous" that some remained in prison as he signed their pardons.

Zoom in: Among those convicted under the Freedom of Access to Clinic Entrances Act and pardoned by Trump was Lauren Handy, 31, who was sentenced to nearly five years in prison for leading the blockade that prosecutors said resulted in a nurse spraining her ankle.

• Police found fetuses at Handy's Capitol Hill home, which anti-abortion activists said related to illegal late-term abortions. She was never charged with any offense in relation to this.

Zoom out: Trump signed the pardons one day after the 52nd anniversary of the U.S. Supreme Court establishing the constitutional right to an abortion.

• This ruling, Roe v. Wade, was overturned in a majority Supreme Court decision in 2022 that Trump took credit for.
• Trump said during the 2024 presidential campaign that abortion laws should be left to states to decide, but did not endorse a national abortion ban after earlier hinting that he would support one.

Flashback... Vance: GOP has to earn America's trust back on abortion

Editor's note: This article has been updated with more context.

President Trump plans to have a "whole big discussion very shortly" on the Federal Emergency Management Agency because he'd "rather see the states take care of their own problems," according to an interview broadcast Wednesday evening.

Why it matters: Trump has signed a multitude of executive orders since taking office again on Monday and he indicated on Fox News in his first interview since being inaugurated that he could have FEMA in his sights.

• Trump and others in the GOP have in recent months complained that FEMA's disaster response has been biased against Republicans.

Driving the news: "The FEMA is getting in the way of everything," Trump said on Fox News' "Hannity."

• "FEMA is a whole 'nother discussion because all it does is complicate everything," he told Fox News' Sean Hannity in the prerecorded interview.
• "FEMA has not done their job for the last four years."
• Trump gave the example of if Oklahoma were hit by a tornado, then the state should be allowed to respond "and then the federal government can help them out with the money."

Flashback: After Trump and others amplified claims that FEMA's response to Hurricane Helene was biased against Republicans affected by the storm in North Carolina and that money for those impacted was diverted to housing for illegal immigrants, the agency launched a fact-checking page on its storm response.

Between the lines: Trump's suggestion would require a major shakeup in emergency response, given how Congress has expanded FEMA's authority by assigning responsibilities to it, codifying it in various laws.

• But given how his administration has moved to crack down on undocumented immigrants and stamp out federal diversity, equity and inclusion (DEI) programs during his first week back in office, such an overhaul cannot be ruled out.
• Project 2025 suggests "reforming FEMA emergency spending to shift the majority of preparedness and response costs to states and localities instead of the federal government" — though during the 2024 campaign Trump disavowed the Heritage Foundation-backed blueprint that some of his Cabinet picks have ties to.

Zoom in: FEMA employs over 20,000 people nationwide, with headquarters in D.C. and 10 regional offices, as the agency responds to disasters and other emergency situations by providing financial and on-the-ground assistance.

• It was officially created in a 1979 executive order by then-President Carter and became part of the Department of Homeland Security in 2003, according to the agency's website.
• Congress passed legislation in 2006 that established FEMA as a distinct agency within DHS following the devastating Hurricane Katrina the previous year.

Zoom out: Trump also discussed with Hannity his planned Friday visits to wildfire-hit California and North Carolina — where FEMA announced Monday it was extending its Transitional Sheltering Assistance program for two months in response to the state's request for further assistance for families displaced by Hurricane Helene.

• As Southern California faces fresh wildfire threats, Trump told Hannity "I don't think we should give California anything until they let water flow down into their system."
• Representatives for Trump did not immediately respond to Axios' request for comment in the evening.

Fresh California wildfires ignited in Southern California on Thursday during "critical" fire weather, leaving tens of thousands of people under evacuation orders.

The big picture: The Hughes Fire, north of Los Angeles, and San Diego County's Border 2 Fire were among the biggest threats as the destructive Eaton and Palisades fires continued to burn during the fourth straight day of red flag warnings amid dry, windy conditions.

State of play: The Hughes Fire grew to 10,396 acres by Thursday night and was 36% contained after igniting a day earlier in Los Angeles County and spreading across over 5,000 acres to Ventura County — making it the biggest and fastest-spreading wildfire since the Eaton and Palisades fires erupted on Jan. 7.

• LA County Sheriff Robert Luna said at a Wednesday briefing that some 31,000 people were under mandatory evacuation orders and a further 23,000 were under evacuation warnings in the fire that's near the popular water reservoir Castaic Lake, some 40 miles from the Palisades and Eaton fires.
• The blaze in the San Gabriel Mountains prompted authorities on Wednesday to temporarily close all northbound lanes on Interstate 5 from just north of State Route 126 and issue smoke, windblown dust and ash advisories.

In San Diego County, the Border 2 Fire was burning out of control across some 600 acres after exploding in size following its ignition about 2:30pm Thursday.

• The county has seen at least seven fires this week, some of which prompted since-lifted evacuation orders. However, Axios San Diego's Kate Murphy notes this blaze is by far the biggest.

Zoom in: Other wildfires that started on Thursday included the Sepulveda Fire, which triggered evacuation warnings after igniting around 12:30am near LA's Getty Center and the UCLA campus.

• The warnings were later lifted as firefighters managed to get the blaze to 60% containment over 45 acres despite facing dry, warm and gusty conditions from Santa Ana winds.
• The Laguna Fire ignited in Ventura County later Thursday morning and was at 70% containment over 94 acres.

Meanwhile, firefighters continued tackling the destructive and deadly Palisades and Eaton fires in Los Angeles County despite the challenging conditions.

• The Palisades Fire was burning across 23,448 acres at 75% containment on Wednesday night.
• The Eaton Fire remained unchanged from Wednesday, across 14,021 acres at 95% containment.

Between the lines: This extreme weather event is partly related to the Arctic blast that's been impacting most of the Lower 48 states, with cold air surging into the Great Basin helping to fuel dry, offshore winds across Southern California.

• The region is suffering from hydroclimate whiplash worsened by human-caused climate change, having seen two wet winters followed by a bone-dry, unusually hot spring, summer and fall.
• Many parts of Southern California have had their driest start to the wet season on record. Only 0.16 inches of rain has fallen in LA since May 6.
• Much of the region has been experiencing "moderate drought" conditions, per the U.S. Drought Monitor.

What's next: A cooling trend was expected to begin on Friday and "turn significantly cooler over the weekend as a cold storm system moves over the region," per an NWS LA forecast discussion.

• LA County on X urged residents to "prepare for potential flooding, mudslides & debris run-off" over the weekend due to "an increased chance of mud & debris flow in recent burn areas."

A rare winter storm that's slamming the southern U.S. with "dangerously cold temperatures," historic snow and icy conditions has been linked to at least 10 deaths as it disrupts travel across the region.

The big picture: Schools, government offices and roads across the region closed and thousands of flights were delayed or canceled due to the cold weather that's brought record snowfall to places including New Orleans, Louisiana; Mobile, Alabama; and Pensacola, Florida.

• Lake Charles, La., saw its first-ever blizzard warning on Tuesday due to heavy snow and high winds from the extreme weather that's tied to the polar vortex event across the Lower 48 states, as it left some 300 million people under cold weather alerts.

Threat level: Rare winter storm and blizzard warnings and advisories stretched from South Texas to Jacksonville, Florida.

• The once-in-a-generation winter storm with "heavy snow, sleet, and freezing rain" was spreading eastward from parts of the Florida Panhandle through the eastern Carolinas, per a National Weather Service forecast discussion.
• "Major highway and air traffic disruptions, including possible road closures and flight cancellations, may continue for several days even after the snowfall ends," the NWS noted.
• "The Arctic Air Mass will create widespread sub-freezing overnight lows along the Gulf Coast and throughout the Southeast. The cold weather will exacerbate power outages," it added.
• "From Tuesday evening into Wednesday, 0.10 inches of freezing rain will develop across northeastern Florida and southeastern Georgia."

Situation report: States of emergency were declared in states including Alabama, Florida, Georgia, Louisiana and Mississippi ahead of the extreme weather event, but storm-related deaths have been reported across the region.

• Five deaths were reported in a vehicle crash on a highway between La Pryor and Batesville in Zavala County, Texas, on Tuesday morning.
• The Dale County, Alabama coroner confirmed two storm-related deaths.
• Austin-Travis County emergency officials "have responded to more than a dozen cold exposure calls since Monday, including two fatal incidents," per a city of Austin, Texas, statement
• Georgia officials said at least one person had died of hypothermia in the Atlanta area.

Zoom in: Winter weather warnings are impacting areas not usually affected by extreme cold, with the NWS Jacksonville noting on X that southeast Georgia into northeastern Florida among the areas facing snow, sleet and ice.

• The Jacksonville Sheriff's Office in a Facebook post urged people to stay off the roads if possible Tuesday night into Wednesday.
• "We are expecting some winter weather we're not used to in Northeast Florida," per the post. "The safest place you can be Tuesday night and Wednesday is at home!"

Zoom out: "Bitterly cold" high pressure extended from the Ohio Valley to the Southern Plains, bringing temperatures 25 to 30 degrees below average for parts of the Mid-Atlantic in addition to the Central Gulf Coast, per the NWS.

• New York Gov. Kathy Hochul declared a state of emergency in 13 counties on Tuesday, with communities near Lake Ontario forecast to receive up to 3 feet of snow and those in the state's west up to 2 feet.

Between the lines: Studies suggest that polar vortex shifts over longer timescales may be more likely because of human-caused climate change, per Axios' Andrew Freedman, who notes this is an area of active research.

• Despite this extreme weather event, the Environmental Protection Agency notes that total snowfall has fallen in many parts of the U.S. since widespread observations began in 1930.
• "In addition to changing the overall rate of precipitation, climate change can lead to changes in the type of precipitation," per the EPA.
• "One reason for the decline in total snowfall is because more winter precipitation is falling in the form of rain instead of snow."

The Trump administration is directing agencies to move to close federal diversity, equity and inclusion offices and place DEI staff on paid leave by 5pm Wednesday ET ahead of being laid off.

The big picture: The memorandum that the Office of Personnel Management sent to federal agencies on Tuesday follows President Trump's signing of an executive order a day earlier to dismantle DEI initiatives within the federal government.

Details: The OPM's memo instructs agencies to take offline all websites and social media accounts associated with DEI by the Wednesday deadline.

• The next action is for agencies to report on steps taken to implement the order by 12pm Thursday ET.
• This includes providing a "complete list" of DEI offices and workers as of Election Day 2024, according to the memo.
• The agencies must provide a written plan for "executing reduction-in-force action" for DEI employees by 5pm Friday ET, the memo says.

What they're saying: "President Trump campaigned on ending the scourge of DEI from our federal government and returning America to a merit based society where people are hired based on their skills, not for the color of their skin," said White House press secretary Karoline Leavitt in a media statement.

• "This is another win for Americans of all races, religions and creeds. Promises made, promises kept."
• Trump in Monday's order calling for the termination of all federal government DEI programs described the Biden administration initiatives to increase diversity, equity and inclusion as "illegal and immoral discrimination programs."

Zoom out: Companies have in recent months responded to Republican lawmakers and activists railing against DEI by rolling back programs.

President-elect Trump pledged during a pre-inauguration victory rally in Washington, D.C. to act when he begins his second term starting Monday "with historic speed and strength and fix every single crisis facing our country."

The big picture: Trump claimed at Sunday's rally in Capital One Arena on the eve of his inauguration that "before even taking office, you are already seeing results that nobody expected to see."

State of play: Trump pointed to a surging stock market, optimism among small businesses, Bitcoin's record highs, among other positive news that's happened in recent months.

• "And as of today, TikTok, is back," he said, in reference to the company's move to restore the video app in the U.S. after Trump vowed to sign an executive order on his first day in office to delay enforcing the ban of the platform that's owned by Chinese firm ByteDance.
• Trump also highlighted the Gaza ceasefire that saw Hamas release three Israeli hostages on Sunday, which Axios' Barak Ravid reports wouldn't have been possible without unprecedented coordination between President Biden's and Trump's teams.
• "This agreement could only have happened as a result of our historic victory in November," Trump said.

Zoom in: Trump promised during his speech that people are "going to see executive orders that are going to make you extremely happy, lots of them" when he takes office on Monday and renewed his vow for a hardline crackdown on immigration.

• "I will outline in my inaugural address tomorrow ... the most aggressive, sweeping effort to restore our borders the world has ever seen," Trump said.

Apple is suspending its new artificial intelligence feature summarizing alerts for news and entertainment apps after facing complaints from news outlets and press freedom groups about generating false and inaccurate information.

Why it matters: The BBC lodged an official complaint after the Apple Intelligence summaries generated an inaccurate headline of a report by the British outlet that incorrectly represented a report on Luigi Mangione, the suspect in last month's killing of UnitedHealthcare CEO Brian Thompson, by suggesting he had committed suicide.

• It's the latest in a series of problematic rollouts of AI features by tech giants, with Microsoft in June announcing changes to its Recall feature following criticism from security and privacy experts.
• Google paused AI image generation last February following complaints about diversity.

Driving the news: Following the BBC false headline controversy, the nonprofit Reporters Without Borders called generative AI services "a danger to the public's right to reliable information on current affairs."

• Meanwhile, the U.K.-based National Union of Journalists called on Apple to swiftly remove the feature, saying: "At a time where access to accurate reporting has never been more important, the public must not be placed in a position of second-guessing the accuracy of news they receive."
• The BBC reported at the time that three news stories on different matters by the New York Times on Nov. 21 "were grouped together in one notification," with one stating that Israel's Prime Minister Benjamin Netanyahu had been "arrested."

What they're saying: "With the latest beta software releases of iOS 18.3, iPadOS 18.3, and macOS Sequoia 15.3, Notification summaries for the News & Entertainment category will be temporarily unavailable," per an Apple statement emailed on Thursday evening.

• "We are working on improvements and will make them available in a future software update."

What to expect: Apple is deploying updates to make clear, using italicized text, that enabling notification summaries activates a beta feature, which may occasionally produce unexpected results.

• Users will be able to manage this feature from the lock screen.

China's leader Xi Jinping is sending a top envoy to attend President-elect Trump's inauguration in Washington, D.C., on Monday, Beijing confirmed.

Why it matters: The "unprecedented" deployment of Xi's special representative, Vice President Han Zheng, is intended to reduce tensions with the U.S. after Trump threatened to impose major tariffs on China and other countries, per the Financial Times, which first reported the news.

• Trump invited Xi to attend his inauguration ceremony to create "an open dialogue with leaders of countries that are not just our allies but our adversaries and our competitors, too," incoming White House press secretary Karoline Leavitt told Fox News last month.

What they're saying: "China follows the principles of mutual respect, peaceful coexistence and win-win cooperation in viewing and growing its relationship with the United States," per a Chinese Foreign Ministry statement posted Friday morning local time.

• "We stand ready to work with the new U.S. government to enhance dialogue and communication, properly manage differences, expand mutually beneficial cooperation, jointly pursue a stable, healthy and sustainable China-U.S. relationship and find the right way for the two countries to get along with each other."

Flashback: Beijing's actions are in stark contrast to President Biden's Inauguration Day four years ago, when Beijing imposed sanctions on officials from the first Trump administration.

President Biden in his farewell address to the nation on Wednesday took aim at Big Tech and warned of "dangerous consequences" if a "concentration of power in the hands of a very few ultra-wealthy people" goes unchecked.

Why it matters: Biden's warning that an "oligarchy" was "taking shape in America" comes as the world's richest person, Elon Musk, prepares to co-lead the incoming Trump administration's new Department of Government Efficiency (DOGE) as his companies including SpaceX hold government contracts.

• Meanwhile, Big Tech CEOs have recently moved to embrace President-elect Trump — with Meta CEO Mark Zuckerberg overhauling longstanding policies and the board of Facebook and Instagram's parent company to be more Trump-friendly.

What he's saying: In his address, Biden pointed to President Dwight Eisenhower's 1961 farewell address in which he warned of "military-industrial complex" and "'the potential for the disastrous rise of misplaced power."

• Six decades later, Biden said he's "equally concerned about the potential rise of a tech industrial complex."
• Americans "are being buried under an avalanche of misinformation and disinformation enabling the abuse of power," Biden said.
• "The free press is crumbling. Errors are disappearing. Social media is giving up on fact-checking," added Biden, in reference to Meta's move to replace checking facts with X-style community notes.
• "The truth is smothered by lies told for power and for profit."

Of note: Biden called artificial intelligence the "most consequential technology of our time, perhaps of all time."

• He added: "AI could spawn new threats to our rights, our way of life, our privacy, how we work and how we protect our nation."

President-elect Trump will move to "preserve" TikTok, said his pick for national security adviser, Rep. Michael Waltz (R-Fla.), on Wednesday — as a potential nationwide ban looms.

The big picture: It's not immediately clear what action Trump could take if the U.S. Supreme Court were to uphold a bipartisan law that would, unless sold to a U.S. firm, ban the popular video app that's owned by Chinese company ByteDance.

• The justices seem inclined to uphold the law, which could take effect as soon as this Sunday.

Driving the news: Fox News' Bret Baier asked Waltz in an interview Wednesday about how true a Washington Post report headlined "Trump considers executive order hoping to 'save TikTok' from ban or sale in U.S. law" was.

• "If the Supreme Court comes out with a ruling in favor of the law, President Trump has been very clear," Waltz said on Fox News' "Special Report."
• "Number one, TikTok is a great platform that many Americans use, and was great for his campaign in getting his message out. But, number two, he is going to protect their data," he said. 
• "We're going to find a way to preserve it but protect people's data. And that's the deal that will be in front of us."

Zoom in: Waltz acknowledged there are "people out there who don't want the U.S. government seeing all their data and passwords" and "we certainly don't want the Chinese government seeing all their data and passwords."

• But he said that Trump "is a dealmaker," adding: "I don't want to get ahead of our executive orders but we're going to create the space to — to put that deal in place."

Between the lines: University of Minnesota law professor Alan Rozenshtein told the Washington Post Wednesday that executive orders were "not magical documents" that would stop a ban from going into effect.

• "TikTok will still be banned, and it will still be illegal for Apple and Google to do business with them," said Rozenshtein, a former national security adviser to the Justice Department.
• "But it will make the president's intention not to enforce the law that much more official."

State of play: President Biden signed into law a bill that passed last year requiring ByteDance to either sell TikTok to an American company or shut down operations in the U.S. by Jan. 19.

• Trump asked the Supreme Court last month to pause the TikTok ban after previously advocating for one before flip-flopping.
• During oral arguments last week, most of the justices focused on the fact that under the law, TikTok could continue operations if it used an algorithm other than ByteDance's and that as a Chinese company it doesn't have First Amendment rights, per Axios' Sam Baker.

What we're watching: Biden could push the ban's deadline by 90 days if ByteDance makes progress toward divestiture in the U.S. by Sunday, the day before Trump's inauguration.

• Rozenshtein noted on X Wednesday that the Supreme Court's website suggests it will release an order list on Tuesday, two days after the law is due to take effect.
• "So they might let the law go into effect without actually saying anything either way," he added.

Southwest Airlines is being sued and Frontier Airlines fined over chronic flight delays by the Department of Transportation, the DOT announced Wednesday.

Why it matters: Wednesday's announcement by the outgoing Biden administration's Transportation Secretary, Pete Buttigieg, comes days after the DOT fined JetBlue $2 million for chronic flight delays — the first time such a penalty had been imposed on an airline.

What we're watching: When asked for comment Wednesday evening on whether Southwest would petition the incoming Trump administration to withdraw the lawsuit, company spokesperson Lynn Lunsford said the airline "has kept an open dialogue with DOT and continues to invite the agency to engage in discussions about a reasonable settlement."

Driving the news: The U.S. Government and Buttigieg are seeking maximum penalties against Southwest for allegedly illegally operating multiple chronically delayed flights, per the lawsuit that was filed in the U.S. District Court for the Northern District of California on Wednesday.

• DOT alleges an investigation found that Southwest operated two "chronically delayed" services between April and August 2022 that resulted in 180 flight disruptions for passengers.
• Each flight between Chicago Midway International Airport and Oakland, Calif., as well as between Baltimore, Md., and Cleveland, Ohio, was chronically delayed for five consecutive months, according to the suit.

Separately, DOT issued Frontier Airlines a fine for "operating multiple chronically delayed flights."

• The airline faces $650,000 in civil penalties with $325,000 to be paid to the U.S. Treasury, per a DOT statement.
• The remaining $325,000 will be suspended if the carrier avoids operating any chronically delayed flights over the next three years.

What they're saying: "Airlines have a legal obligation to ensure that their flight schedules provide travelers with realistic departure and arrival times. Today's action sends a message to all airlines that the Department is prepared to go to court in order to enforce passenger protections," Buttigieg said in a statement.

• Lunsford said via email the airline was "disappointed that DOT chose to file a lawsuit over two flights that occurred more than two years ago" and noted there had been no other violations of the department's Chronically Delayed Flight policy since it was issued in 2009.
• "Any claim that these two flights represent an unrealistic schedule is simply not credible when compared with our performance over the past 15 years," she said. "In 2024, Southwest led the industry by completing more than 99% of its flights without cancellation."
• Representatives for Frontier declined to comment and representatives for President-elect Trump did not immediately respond to Axios' request for comment in the evening.
