Republican colleagues of Rep. Matt Gaetz are seeking to expel him from office as the outspoken Florida lawmaker spearheads an effort to remove House Speaker Kevin McCarthy.

Gaetz has pledged to file a motion to vacate the speakership of Kevin McCarthy, a Republican from California.

Long frustrated with Gaetz, who has consistently criticized GOP leadership and undermined his own party, some Republicans are eager to expel him if the House Ethics Committee, currently investigating him, finds evidence of wrongdoing, according to a report by Fox News on Sunday.

“No one can stand him at this point. A smart guy without morals,” one lawmaker told the outlet.

Gaetz, who is rumored to be considering a run for Florida governor, downplayed the threat by posting a “Game of Thrones” meme.
