Former Kentucky Attorney General Daniel Cameron on Thursday announced that he is running to replace Sen. Mitch McConnell, R-Ky., in the upper chamber of Congress. 

Cameron, who was Kentucky's first Black attorney general, announced his Senate campaign just minutes after McConnell said he would not seek re-election in 2026. 

"Kentucky, it's time for a new generation of leadership in the U.S. Senate. Let's do this," Cameron wrote on X, sharing a screenshot of himself, his wife and their children seen on the Daniel Cameron U.S. Senate campaign website. 

Fox News Digital reached out to Cameron's campaign for comment but did not immediately hear back. 

‘GOOD RIDDANCE': MAGA REACTS TO ‘RINO’ MITCH MCCONNELL SENATE EXIT

A seven-term senator, McConnell announced on his 83rd birthday that he would not seek re-election and would retire at the end of his term. McConnell recently voted against several of President Donald Trump's Cabinet picks: National Intelligence Director Tulsi Gabbard, Health and Human Services Secretary Robert F. Kennedy, Jr. and Defense Secretary Pete Hegseth. McConnell voted in favor of Kash Patel, whom the Senate confirmed as Trump's FBI director on Thursday.

In a statement obtained by Fox News Digital, National Republican Senatorial Committee (NRSC) Chair Tim Scott, R-S.C., said McConnell has "dedicated his life to public service and the state he loves" and "our country is grateful for his leadership and legacy of confirming conservative judges and justices, and safeguarding the Republican Senate Majority." 

"Kentucky is a red state, so the NRSC is confident that our eventual nominee will be a principled, America First conservative who will join our Majority’s fight for our nation’s Golden Era," Scott said. 

Cameron has long been groomed to become McConnell's replacement. He unsuccessfully ran for governor in 2023 against two-term Democrat Andy Beshear. 

In his first year as attorney general, Cameron handled the investigation into Breonna Taylor's shooting death during a March 2020 Louisville police raid at a time when George Floyd-era protests and riots swept the nation.

His office ultimately declined to charge two officers who opened fire, but indicted a third on wanton endangerment over bullets that entered a neighbor's apartment. That officer was acquitted in a state trial, but the Justice Department brought federal charges against all three. 

SEN MITCH MCCONNELL ANNOUNCES HE WILL NOT RUN FOR RE-ELECTION

Cameron, the current CEO of the 1792 Exchange, a non-profit that aims to hold companies accountable for pushing a "far-left ideology," might face GOP primary competition.

Rep. Andy Barr, R-Ky., reiterated Thursday that he is "considering running for Senate because Kentucky deserves a Senator who will fight for President Trump and the America First Agenda." 

"I’ve done that every day in the House and would do so in the Senate," Barr said. "I’m encouraged by the outpouring of support and my family and I will be making a decision about our future soon." 

Nate Morris, an entrepreneur serving as chairman and CEO of the Louisville-based Morris Industries, said last week he was still considering a run for McConnell's seat, while slamming other potential candidates waiting for McConnell to back out first.

"If you're asking for a permission slip to run for office here in Kentucky from Mitch McConnell, then you shouldn't be running in the first place," Morris said. "The last thing Kentucky needs is another puppet for Mitch McConnell running for office."

As for Democrats, Beshear's spokesman Eric Hyers said in a post on X that the governor would not be running to fill McConnell's seat. 

Democratic state Rep. Pamela Stevenson of Louisville has long been fundraising to run for McConnell's seat, according to the Courier Journal. 

Kentucky leans red in federal elections, such as Senate races, but has been more competitive during gubernatorial contests.

EXCLUSIVE: A conservative legal watchdog is expected to file a brief with a Kentucky court to urge a judge against blessing a consent decree forged by Attorney General Merrick Garland and the city of Louisville and Jefferson County, Ky., that would reform police practices after the controversial 2020 death of Breonna Taylor.

The Oversight Project is placing its amicus brief on the docket of the U.S. District Court for the Western District of Kentucky on Friday morning as a judge prepares a schedule to rule on activating the agreement.

Oversight Project Executive Director Mike Howell said the consent decree includes a "laundry list of BLM-type standards that have been argued for over the years since George Floyd['s death in 2020]" and the riots that followed.

"Louisville would be a sanctuary city for gangbangers," Howell warned, adding he hopes Friday’s addition to the docket gives the court pause before agreeing to any accelerated timeline for approval.

PROPOSED CHICAGO POLICE RESOURCE CUTS COULD LAND CITY IN COURT UNDER CONSENT DECREE, OFFICIALS WARN

Taylor was killed in a hail of police gunfire after Louisville officers sought to serve a drug warrant at her boyfriend Kenneth Walker’s house, when her beau fired a "warning shot" through the door and struck Officer Jonathan Mattingly in the leg.

A hail of return fire followed, fatally wounding Taylor, and five officers were later involved in legal cases where one was found guilty of deprivation of rights under the color of law for reportedly firing blindly through a window amid the chaos.

Walker later alleged he mistook the police for intruders and did not hear them announce themselves. Louisville wound up paying Taylor’s family $12 million in a wrongful death settlement.

Last week, Garland announced the consent decree with Louisville, saying it will bring about needed systemic reforms to policing to prevent a repeat of what happened to Taylor.

Howell said, however, that the decree will only hamstring the police department and also defy the will of Kentucky voters who elected new Republicans on the Louisville council on the issue of law and order.

"[The decree] basically limits the ability for officers to react quickly and in a strong way. It's very heavy on the de-escalation techniques, particularly as it relates to this category of people who they call ‘behaviorally impaired’ or something to that effect," Howell said.

BIDEN ADMIN HIT WITH FOIA SEEKING 25TH AMENDMENT-RELATED COMMS

Howell said there is concern over the spiking teenage murder rate – violence committed by suspects aged 11-17 – and that the decree wrongly imposes new standards for dealing with youth offenders as well as stop-and-frisk restrictions.

One of the most glaring issues with the agreement is the fact Louisville councilmen, Kentucky lawmakers and the general public will all be prevented from making further adjustments to policing policies for five years, if the judge signs the decree.

In a consent decree system, an official monitor appointed by the judge, and not the relevant legislature, is the arbiter of policies that fall under said agreement unless both parties that forged it agree to change them.

Howell said, in that regard, the Biden Justice Department and Louisville Mayor Craig Greenberg, a Democrat, appear to be rushing through the legal process to head off the likelihood a Trump Justice Department will balk at the agreement.

"The most basic responsibility of government is to keep our people safe while protecting constitutional rights and treating everyone fairly," Greenberg said in a statement about the decree. "As mayor, I promised to uphold that responsibility, and I have."

"The Department of Justice saw the action we’ve already taken and our commitment to aggressively implement police reform. As a result of these improvements, we have a consent decree unlike any other city in America."

Greenberg said any decree must build on reforms made in recent years, cannot "handcuff police as they work to prevent crime" and also be financially responsible and have a clear sunset date.

"I felt comfortable signing this because our officers will have clear guidance and goals to meet, the DOJ can’t move the goalposts, and our officers can focus on good police work, not paperwork," added Louisville Police Chief Paul Humphrey.

The Oversight Project’s amicus brief is backed by law enforcement advocacy leaders like Jason Johnson, president of the Law Enforcement Legal Defense Fund.

Johnson, whose group promotes constitutional policing and studies similar consent decrees, told Fox News Digital it's clear the Biden DOJ realizes such an agreement would be "D.O.A." when President-elect Donald Trump assumes the Oval Office. 

"Most of these police consent decrees are more of an activist wish list than effective means to remedy constitutional violations by police agencies. The Justice Department is trying to impose burdensome rules that far exceed their authority under law," Johnson said.

He suggested that technical assistance letters, which aim to encourage reforms without imposing a judicial arbiter, are generally preferred in most cases.

"But, the activist lawyers in the Biden administration prefer to use a sledgehammer instead of a scalpel. This approach has proven counterproductive time and again — hurting public safety, police morale, and police-community relations more than it helps."

Meanwhile, Howell said he hopes the Kentucky judge will see that Greenberg and Garland are trying to "turn him into a legislature" when it comes to law enforcement practices.

Under the consent decree system, the policy changes will be untouchable by a more hawkish Trump DOJ for up to five years, rendering the new administration’s predicted actions in the law enforcement realm moot in Louisville.

Criminals will likely endorse the decree, he said, as they will use the encyclopedia of new policing standards to their benefit.
