US GOP Congresswoman Marjorie Taylor Greene announced her resignation in a lengthy statement on social media on Friday, following a public fallout with US President Donald Trump.

Greene's last day in office will be January 5, according to the statement.

"My only goal and desire has ever been to hold the Republican Party accountable for the promises it makes to the American people and put America First," Greene's statement read, boasting "one of the most conservative voting records in Congress."

Greene declared that her career has brought on "years of nonstop, never-ending personal attacks, death threats, lawfare, ridiculous slander, and lies about me, that most people could never withstand."

She alleged that Trump "hatefully dumped tens of millions of dollars against [her]" and tried to "destroy" her, calling the turn of events "absurd and completely unserious."

Trump called Greene's resignation "great news for the country" in an interview with ABC News on Friday, according to Reuters.

On November 14, Trump withdrew his endorsement of Greene, saying he was "fed up with her and her antics" in a statement released on Truth Social.

"All I see 'Wacky' Marjorie do is COMPLAIN, COMPLAIN, COMPLAIN!" Trump said, claiming that the feud began when he told Greene she should not run for Governor or Senator, and "didn’t have a chance" to win without his endorsement.

Greene, a long-time advocate for Trump's Make America Great Again (MAGA) movement, stated she "fought harder than almost any other elected Republican to elect Donald Trump and Republicans to power" and spent millions of her own money to aid Trump's campaign.

She cited having "too much self-respect and dignity" to continue to endure a "hurtful and hateful primary" launched by the president and declared that once "the common American people finally realize and understand that the Political Industrial Complex of both parties is ripping this country apart," she will be by their side to "rebuild it."
