Marjorie Taylor Greene (Ga.) has been kicked out of the House Freedom Caucus, a historic development that comes after months of growing tensions within the GOP's pro-Trump wing.

Greene's expulsion, a first for the Freedom Caucus, came after she disrespected one of the group's most vocal members, Lauren Boebert (R-Co.).

The vote to remove Greene happened last month, just days after her altercation with Boebert.

"A vote was taken to remove Marjorie Taylor Greene from the House Freedom Caucus for some of the things she’s done," Andy Harris (R-Md.) told Politico. 

MTG expelled

Greene snapped at Boebert after she unilaterally moved to impeach Biden over the southern border.

At the time, Greene did not deny calling Boebert a "b----" on the House floor, and she also accused her of copying her impeachment articles.

"I’ve donated to you, I’ve defended you. But you’ve been nothing but a little b---- to me,” Greene told Boebert at the time. "And you copied my articles of impeachment after I asked you to cosponsor them.”

The flare-up followed months of intraparty drama surrounding House Speaker Kevin McCarthy (R-Ca.), an ally of Greene and President Trump.

McCarthy is not trusted by the party's right flank, which sees him as too cozy with the establishment. The Freedom Caucus has held his feet to the fire since making him endure a humiliating and drawn-out fight for the Speaker's gavel in January.

Outrage with McCarthy erupted again after he negotiated a debt ceiling deal that conservatives rejected as a betrayal of his promise to cut spending.

Last straw

Disagreements about McCarthy's leadership played a role in the vote to expel Greene, but the straw that broke the camel's back was Greene's foul-mouthed exchange with Boebert, Harris said.

“I think the way she referred to a fellow member was probably not the way we expect our members to refer to other fellow, especially female, members,” Harris said.

Greene, or "MTG" as she is known, quickly became a lightning rod of criticism after she entered Congress in 2021.

Democrats and some Republicans took the controversial step of removing her from committee assignments when she was just weeks on the job - a move Republicans have since repaid by censuring Adam Schiff (D-Ca.) and kicking him off the House Intelligence Committee.
