• Jay Clayton, the top federal prosecutor in Luigi Mangione's case, has been recused.
• Trump nominated Jay Clayton as interim US attorney for the Southern District of New York this month.
• The Justice Department is seeking the death penalty for Mangione.

The top federal prosecutor in Luigi Mangione's federal case has been recused.

The US Attorney's Office for the Southern District of New York shared the update in a letter addressed to Judge Margaret M. Garnett on Wednesday.

"The Government also writes to inform the Court that United States Attorney for the Southern District of New York, Jay Clayton, is recused from this matter," the letter said.

The Southern District of New York did not say why Clayton was recused. Instead, Perry A. Carbone, the district's criminal division chief, will act as the attorney for the United States in the case.

Mangione, 26, is accused of shooting and killing UnitedHealthcare CEO Brian Thompson in December 2024. He faces charges in three different jurisdictions.

In New York, he faces state charges of murder as an act of terror. He also faces lesser state charges for forgery and weapons violations in Pennsylvania, where he was arrested days after the shooting.

Mangione also faces federal charges for murder through the use of a firearm, among other charges. The Justice Department is seeking the death penalty against Mangione for the federal murder charge. He has pleaded not guilty to all charges.

Clayton was chairman of the Securities and Exchange Commission from 2017 to 2020. He previously worked as a lawyer for Sullivan & Cromwell.

President Donald Trump unsuccessfully attempted to install Clayton as the Southern District of New York's lead attorney in 2020. Trump nominated Clayton for the role a second time last November, which drew ire from Democrats like Sen. Chuck Schumer, who said he would block Clayton's nomination, according to Bloomberg Law.

Edward Y. Kim served as the acting US attorney for the Southern District of New York from December 2024 to January, when Danielle Sassoon took over the interim position, the Associated Press reported. Sassoon resigned in February, and Matthew Podolsky took over before stepping down this month, according to ABC News.

On April 16, Trump named Clayton the interim US Attorney for the Southern District of New York, making his recusal from this district's most prominent case notable.

Representatives for the Southern District of New York and the US Attorney's Office did not immediately respond to a request for comment from Business Insider.

• Humanoid robots ran a half-marathon against humans for the first time on Saturday in Beijing.
• The race highlighted how far humanoid robots have advanced, and how far they still have to go.
• While some robots finished the race, others stumbled. They all required human handlers.

More than 12,000 people and 21 humanoid robots gathered in Beijing on Saturday morning to compete in a half-marathon.

Yes, robots.

Machine battled muscle across 13 miles during the 2025 Beijing E-Town Half Marathon and Humanoid Robot Half Marathon, which organizers said was the first of its kind.

The participating robots raced in a separate lane from humans and came in different designs.

Noetix Robotics showed off the N2, an over 40-pound humanoid robot about 3 feet tall. Unitree Robotics entered its G1 model, which weighs nearly 80 pounds and stands over 4 feet tall. Another robot running in the race featured a woman's face. Engineers or human handlers accompanied the robots.

The People's Government of Beijing Municipality said on its website that the robotic marathoners underwent "intensive training, " including "late-night endurance drills," ahead of the race.

During a March press conference, Li Quan, deputy head of the Beijing Economic-Technological Development Area, said the robots were given about three and a half hours to finish the course.

He added that robots could win prizes in three categories: race completion, best endurance, and most popular robot.

Although the human-humanoid half-marathon is a feat, not every robot rose to the occasion. Footage obtained by Reuters showed one robot falling over at the start line while another crashed into a railing and sent its human operator to the ground.

According to The Wall Street Journal, a robot called "Huanhuan" ran in the wrong direction at times before sitting on the ground and refusing to stand.

One robot rose above the rest: Tien Kung Ultra, designed by Beijing Humanoid Robot Innovation Center, became the first humanoid robot to cross the finish line in 2 hours and 40 minutes, the Journal reported.

Li said he hoped the event would be recognized as more than a fun weekend spectacle.

"We hope that this event will not only showcase achievements in the humanoid robotics industry but also spark discussions and deepen the public's understanding of robot capabilities, which will help accelerate industry development," he said in March.

Technological developments, like AI, have allowed humanoid robots to evolve rapidly in recent years. Some companies like Mercedes-Benz and BMW have even partnered with humanoid robot companies to test robots on factory lines, though very few of these robots have been deployed worldwide.

Some in the tech sector consider China to be ahead of the United States in the humanoid robot race, pointing to events like the 2025 Spring Festival Gala in Beijing, which featured 16 AI-powered humanoid robots developed by Unitree, a Chinese company, dancing to traditional folk music with elaborate choreography alongside human dancers.

Tesla CEO Elon Musk, whose company manufactures its own humanoid robot, once said he believed humanoids would outnumber humans by 2040.

• TikTok Shop is now a more popular online retailer than Shein and Sephora among Americans.
• TikTok Shop first launched in September 2023.
• A new consumer trends report found that 45% of surveyed Americans have bought something on TikTok.

TikTok Shop has surpassed retail giants Shein and Sephora in the online battle for US shoppers.

A 2025 consumer trends report by Coefficient Capital and The New Consumer's Dan Frommer analyzed how Americans' spending habits could affect certain brands. The research included 11 surveys of over 3,000 US consumers. The company conducted its most recent survey this month.

TikTok Shop launched in September 2023, making it a relatively new online retailer compared to its peers. However, the consumer trends report said 80% of surveyed Americans who use TikTok at least once a month are aware of TikTok Shop, signaling the retailer's growing reach.

That reach has helped TikTok overtake retailers like Sephora, Shein, and Qurate in US consumer spending for the third financial quarter, according to the trends report.

Sephora and Shein are two popular online retailers in the United States, especially with younger generations like Gen Alpha. Qurate Retail Group owns and operates six retail brands, including QVC. The company sells items online through its brands.

Sephora helped its parent company, LVMH, achieve record-breaking sales in 2023, reaching $10 billion in revenue across North America. Shein made $2 billion in profits that year. Although Qurate's third-quarter earnings report said revenue decreased by 5%, it generated $152 million in operating income.

A March Financial Times report cited three sources who said TikTok had reached $16 billion in sales in the United States. It's unclear how much the TikTok Shop has made since its 2023 launch, but the company said in its 2024 economic report that the app drove $15 billion in revenue for small businesses in the United States.

The consumer trends report said 45% of surveyed Americans purchased "fashion, clothing, and accessories" from TikTok Shop. Beauty and personal care items came second at 44%. Surveyed TikTok users also indicated purchasing electronics, home goods, food, toys, books, and more from the online shop.

TikTok has led the growth of social media shopping apps in the United States in recent years. TikTok's Chinese parent company, ByteDance, likely wants to replicate the success of its sister app in China, Douyin, which drives hundreds of billions in sales annually, often through influencer livestreams.

Despite its rising popularity with content creators and shoppers alike, TikTok faces a potential federal ban in the United States next month.

In April, Congress passed the Protecting Americans from Foreign Adversary Controlled Applications Act. The law gives ByteDance until January 19 to divest from TikTok or face a ban in the United States. On December 6, a federal appeals court upheld the ban as constitutional.

Lawmakers worry that the Chinese government could compel the app's Chinese ownership to manipulate content for propaganda or leverage the personal data of millions of Americans.

Ahead of the potential ban, TikTok launched a "limited-time offer " promotion this week, allowing users to earn $50 in TikTok Shop credits to recruit a new user. Users can earn up to $350 in shop credits in total.

Representatives for TikTok, Shein, Sephora, and Qurate did not respond to a request for comment from Business Insider.

• A gunman fatally shot UnitedHealthcare CEO Brian Thompson on December 4 in New York City.
• The NYPD launched a manhunt but has so far failed to capture the suspect.
• The suspect's evasion has revealed holes in surveillance, but police say it's just a matter of time.

The Manhattan shooting Wednesday of UnitedHealthcare CEO Brian Thompson was captured by a surveillance camera and shared on social media, where the footage racked up hundreds of thousands of views. Authorities later released full-color surveillance images of the gunman, including one that showed him with his mask pulled down and smiling.

Yet, the gunman is still at large after four days despite a citywide manhunt led by the largest metropolitan police force in the country. On Friday, authorities told CNN they believed the gunman had managed to leave the city by bus.

The gunman's ability to evade capture so far has highlighted the limits of surveillance, even in a city like New York, where authorities have access to thousands of cameras that can track millions of people daily.

"You have got to remember, he was running around a city of 9 million people," Joseph Giacolone, a former NYPD Sergeant and professor at the John Jay School of Criminal Justice, told Business Insider. "You know, it's not that easy to pick somebody up the street, especially if they're all buttoned up."

New York City is under constant surveillance by police and residents

After the September 11 terrorist attacks in 2001, George W. Bush's administration expanded surveillance across the country.

Bush signed the Aviation and Transportation Act that November, creating the Transportation Security Administration. That same year, the Bush administration ushered in the USA Patriot Act, which expanded law enforcement's ability to use surveillance.

The US Congress later created the Department of Homeland Security. The department launched a nationwide campaign — "If You See Something, Say Something" — encouraging citizens to report suspicious activity to law enforcement to prevent terrorism and other criminal acts.

Since then, the emphasis on surveillance and security has spread nationwide, including in New York City, where cameras are now everywhere.

Amnesty International, a human rights organization, said there were over 25,500 surveillance cameras in New York City in a 2022 report. The NYPD has used images from the ubiquitous cameras to track crimes and for use in facial recognition software.

The NYPD's "Facial Identification Section" received 9,850 requests for comparison and returned 2,510 possible matches in 2019 — a roughly 25% match rate. The agency said it's unaware of cases in NYC in which a person was falsely arrested due to a facial recognition match.

This May, New York City Mayor Eric Adams launched a pilot program focused on using technology to increase public safety. The "community-based security camera integration platform" will allow businesses to "voluntarily share information in real-time with the NYPD through existing closed-circuit television cameras," according to a press release.

The emergence of Amazon's Ring cameras and smartphones has added another layer of monitoring. In 2022, the NYPD said it would join and monitor the Neighbors app, where residents share information on crime and safety.

"While the NYPD will not monitor the app around the clock, it will have the capacity to view, post and respond to crime- and safety-related information posted publicly by the users of the app," a press release said.

The NYPD is "processing a tremendous amount of evidence"

Commissioner Jessica Tisch told CNN on Friday that the department had already collected "lots of forensic evidence" and was "processing a tremendous amount of evidence in this case."

She said there is also a "massive camera canvass" of the suspect's movements through the city.

Additionally, a law enforcement official told CNN that investigators found a backpack in Central Park they believe belonged to the suspect but had not officially confirmed where it came from. Authorities took the backpack for tests.

Giacolone told BI that while the shooting suspect has evaded capture for now, it will be difficult for him to elude authorities as they collect more evidence. The NYPD will be looking for what he called "the three horsemen of forensics" to solve the case, which are video surveillance, cellphone records, and internet records.

"I've been on these investigations," Giacolone said. "They know what hole he crawled out of, what hole he went back into. As far as I'm concerned, they already know who he is. They just got to find him."
