President Donald Trump on Friday night publicly disavowed Rep. Marjorie Taylor Greene (R-GA), once one of the president’s closest and most committed allies on Capitol Hill, saying he was withdrawing his endorsement of Greene and is prepared to support a primary challenger to the far-right Georgia congresswoman.

Greene, long dogged by controversy for her record of promoting antisemitic and otherwise fringe conspiracy theories, has emerged as one of the most vocal opponents of Israel on the right, accusing the country of genocide and leading efforts attempting to cut off U.S. aid to the Jewish state.

She has also repeatedly publicly criticized Trump’s policies and Republican leadership on Capitol Hill since the start of the government shutdown, earning Trump’s ire. Her breaks with the GOP have made her into a budding star in liberal media circles, where her ongoing promotion of conspiracy theories has increasingly been overlooked.

Trump said on his Truth Social platform that he has heard that “wonderful, Conservative people are thinking about primarying Marjorie” and that “if the right person runs, they will have my Complete and Unyielding Support,” accusing her of having “gone Far Left.”

Greene’s district is among the most heavily Republican in the country, and losing Trump’s support could prove a significant blow to the congresswoman.

“All I see ‘Wacky’ Marjorie do is COMPLAIN, COMPLAIN, COMPLAIN!” Trump wrote, adding that Greene’s criticism began after he showed her statewide polling that placed her at just 12% support and discouraged her from running for Senate or governor, both positions Greene had been eyeing.

According to NOTUS, Greene is discussing a presidential run in 2028, though she denied that to the publication.

“[Greene] has told many people that she is upset that I don’t return her phone calls anymore, but with 219 Congressmen/women, 53 U.S. Senators, 24 Cabinet Members, almost 200 Counties, and an otherwise normal life to lead, I can’t take a ranting Lunatic’s call every day,” Trump continued in his post.

He later called Greene a “Traitor” and a “disgrace to our GREAT REPUBLICAN PARTY!”

Greene responded on X, saying Trump had lied to her and claiming that two recent text messages about files related to child sex trafficker Jeffrey Epstein had “sent him over the edge,” saying it is “astonishing really how hard he’s fighting to stop the Epstein files from coming out.”

Greene is one of a small number of Republicans cosponsoring a measure to force a vote, over Republicans’ objections on files related to Epstein. Trump, an associate of Epstein, has sought to prevent the full release of those files, calling the push for further disclosure “the Epstein hoax.”

“Most Americans wish he would fight this hard to help the forgotten men and women of America who are fed up with foreign wars and foreign causes, are going broke trying to feed their families, and are losing hope of ever achieving the American dream,” Greene said. “I have supported President Trump with too much of my precious time, too much of my own money, and fought harder for him even when almost all other Republicans turned their back and denounced him. But I don’t worship or serve Donald Trump.”

In a subsequent post, Greene shared a graphic showing she has not received support from pro-Israel groups alongside another graphic comparing her “Liberty Score” to that of Trump-backed pro-Israel Sen. Lindsey Graham (R-SC). In the post, she wrote: “This and the Epstein files is why I’m being attacked by President Trump. It really makes you wonder what is in those files and who and what country is putting so much pressure on him?”

She also claimed that Trump’s posts are driving a wave of security threats against her.

Trump has also worked to defeat Rep. Thomas Massie (R-KY), another of the most vocal anti-Israel Republicans The president has endorsed retired Navy SEAL Ed Gallrein, who is challenging Massie in the GOP primary. 

On Friday, Trump called Massie a “LOSER!” in a separate Truth Social post, claiming that “the Polls have him at less than an 8% chance of winning the Election” and mocked his recent remarriage.
