Matt Gaetz, the former Florida congressman, withdrew from consideration to serve as Donald Trump’s attorney general on Thursday, amid intense scrutiny of allegations of sexual misconduct, ending the brief nomination of one of Trump’s most controversial cabinet picks.

After meeting with senators on Capitol Hill on Wednesday, Gaetz determined that his nomination was “becoming a distraction to the critical work” of the new Trump administration, he explained on X.

“There is no time to waste on a needlessly protracted Washington scuffle, thus I’ll be withdrawing my name from consideration to serve as Attorney General. Trump’s [justice department] must be in place and ready on Day 1,” Gaetz said.

“I remain fully committed to see that Donald J. Trump is the most successful President in history. I will forever be honored that President Trump nominated me to lead the Department of Justice and I’m certain he will Save America.”

A source familiar with Gaetz’s nomination process told the Guardian that privately confirmed opposition from four senators – enough to sink the nomination if no Democrats defected – was what pushed Gaetz to decide to withdraw.

The announcement comes a little more than a week after Trump said he was nominating Gaetz to be attorney general, the chief law enforcement officer of the United States.

A staunch Trump ally disliked by some fellow Republicans in Congress, Gaetz always faced an uphill battle to be confirmed. He came under intense scrutiny last week over allegations he had sexual relations with a 17-year-old girl.

The justice department declined to charge Gaetz last year as part of a sex-trafficking investigation. But details of his encounter and relationships were beginning to seep out. Just before he announced he was withdrawing his nomination, CNN reported that the woman he is alleged to have had sex with when she was 17 told the House ethics committee there had been a second sexual encounter with Gaetz.

ABC News and the New York Times reported earlier this week on records of Venmo transactions connecting Gaetz to women who said that he paid them for sex.

Gaetz’s announcement comes one day after the House ethics committee deadlocked over releasing its report on the allegations. At least one House Democrat on the committee, Representative Sean Casten of Illinois, said on Thursday he would continue to push for the full release of the Gaetz report.

In a post on Truth Social, Trump, who had reportedly been calling senators to lobby for Gaetz’s confirmation, said that “Matt has a wonderful future”.

“I greatly appreciate the recent efforts of Matt Gaetz in seeking approval to be Attorney General,” he wrote. “He was doing very well but, at the same time, did not want to be a distraction for the Administration, for which he has much respect. Matt has a wonderful future, and I look forward to watching all of the great things he will do!”

A staunch Trump ally known for theatrics such as wearing a gas mask on the House floor, Gaetz resigned from Congress the day Trump announced his nomination. It is unclear who Trump will now pick to lead the justice department, which the president-elect has pledged to use to prosecute his enemies.

Gaetz’s withdrawal comes as Trump’s pick to lead the Department of Defense, Pete Hegseth, faces accusations of sexual assault. A police report made public this week contains allegations from a woman regarding a 2017 encounter with Hegseth in which she says he took her phone, blocked her from leaving his hotel room and sexually assaulted her. Hegseth has denied the allegations.

“Matt Gaetz was a ridiculous, horrible and dangerous AG selection. That Republican senators were not willing to rubber-stamp his nomination is a hopeful sign that a modicum of sanity persists in Washington,” said Robert Weissman, co-president of Public Citizen, a watchdog group, in a statement. “But Gaetz was not the only Trump nomination threatening America and there’s every reason to worry about who Trump will appoint in Gaetz’s stead.”
