WASHINGTON — Rep. Marjorie Taylor Greene of Georgia, a supporter of President Donald Trump who has become a critic, said Friday she is resigning from Congress in January.

Greene, in a more than 10-minute video posted online, explained her decision, saying she’s “always been despised in Washington, D.C., and just never fit in.”

Greene’s resignation followed a public fallout with Trump in recent months, as the congresswoman criticized him for his stance on files related to Jeffrey Epstein, along with foreign policy and health care.

Trump branded her a “traitor” and “wacky” and said he would endorse a challenger against her when she ran for reelection next year.

She said her last day would be Jan. 5, 2026.

The White House did not immediately respond to a message seeking comment Friday night.

Greene was one of the most vocal and visible supporters of Trump’s Make America Great Again.

Her decision to step down in the face of his opposition put her on the same track as many of the more moderate establishment Republicans before her who went crosswise with Trump.

Greene had been closely tied to the Republican president since she launched her political career five years ago.

In her video Friday, she underscored her longtime loyalty to Trump except on a few issues, and said it is “unfair and wrong” that he attacked her for disagreeing.

“Loyalty should be a two-way street and we should be able to vote our conscience and represent our district’s interest, because our job title is literally ‘representative,’” she said.

Greene swept to office at the forefront of Trump’s MAGA movement and swiftly became a lightning rod on Capitol Hill for her views.

Over time, she proved a deft legislator, having aligned herself with then-GOP leader Kevin McCarthy, who would go on to become House speaker. She was a trusted voice on the right flank, until McCarthy was ousted in 2023.

While there has been an onslaught of lawmakers from both parties heading for the exits ahead of next fall’s midterm elections, as the House struggles through an often chaotic session, Greene’s announced retirement will ripple throughout the ranks — and raise questions about her next moves.

Greene was first elected to the House in 2020. She initially planned to run in a competitive district in northern Atlanta’s suburbs, but relocated to the much more conservative 14th District in Georgia’s northwest corner.
