Rep. Marjorie Taylor Greene

One of President Donald Trump's most loyal internet defenders has turned on Rep. Marjorie Taylor Greene (R-GA), saying she has betrayed the president with her recent critique of him and the Republican party, Newsweek reports.

The anonymous social media account known as "Cat——", which has 3.9 million followers, complained that the Republican congresswoman had been "stabbing Trump in the back at every turn" and called for her to be primaried.

Last week, Mediaite reported that Greene was no longer following one of its social media accounts "amid a MAGA civil war."

Greene's vocal pushback against the so-called One Big Beautiful Bill Act, the release of files associated with the late convicted sex trafficker Jeffrey Epstein and foreign policy measures has "triggered a backlash from some MAGA influencers," Newsweek says.

Cat—— shared an image claiming Greene had made $21 million in five years in Congress and said it was "time to primary and get rid of this fraud."

They also said Greene, who has said her high net worth comes from her family's construction business and personal investments, was "getting filthy rich while stabbing Trump in the back at every turn."

"I'm so tired of these complete and utter phonies," they wrote, adding in a subsequent post. "Marjorie Taylor Greene is so cringe now. I feel like taking a bath because I ever supported her. She’s a total fraud who’s gotten filthy rich in a few short years in Congress."

Greene doesn't seem to care what they think, telling NBC News earlier this month, “I’m not some sort of blind slave to the president, and I don’t think anyone should be.”
