Rep. Matt Gaetz, R-Fla., did not mince words Tuesday in warning House Speaker Kevin McCarthy, R-Calif., that he could be fired if President Joe Biden is not impeached.

In a radio interview and social media post, Gaetz said if McCarthy resists GOP lawmakers’ efforts to impeach President Joe Biden, he could face a vote to be removed from the speakership. 

“I worked very hard in January to develop a toolkit for House Republicans to use in a productive and positive way,” Gaetz wrote on Truth Social. “I don’t believe we’ve used those tools as effectively as we should have.

“We’ve got to seize the initiative,” he added. “That means forcing votes on impeachment. And if @SpeakerMcCarthy stands in our way, he may not have the job long.”

In his interview with radio host Todd Starnes, Gaetz said Americans he’s spoken with around the country are “disillusioned with House Republicans right now. They think that we have not put up a substantial battle to defeat the worst elements of this Biden administration.”

To secure the votes needed to be elected speaker in January, McCarthy made a number of concessions, including allowing a single member of the House to make a motion to vacate the speakership. A simple majority of the House would need to vote to remove McCarthy.

Some House Republicans are eager to go after Biden over claims of financial misconduct involving his son Hunter, but the Democratic president has not been shown to have done anything wrong.

Joe Biden has called the accusations “a bunch of malarkey.”

McCarthy said last month that an impeachment inquiry was “a natural step forward. Asked by Spectrum News for a response to Gaetz's comments, the speaker's office pointed to the quote.

McCarthy has so far avoided committing to an impeachment vote or offering a timeline for possible action.

The White House attacked Gaetz in a statement Wednesday. 

“On the heels of openly admitting the goal of impeachment isn’t to get to the truth but instead to damage the President politically, Matt Gaetz is yet again confirming that House Republicans’ evidence-free impeachment stunt is being driven by the demands of the most extreme, far-right members of Congress,” White House spokesman Ian Sams said. 

“If Speaker McCarthy opens an impeachment inquiry simply to throw red meat to the right wing, it will yet again prove this is nothing more than a costly, illegitimate, politically-motivated exercise not rooted in reality,” Sams added.

Gaetz is not the only House Republican making threats related to impeaching Biden. Last week, Rep. Marjorie Taylor Greene said she would not support funding the government unless Congress votes to open an impeachment inquiry against the president.
