Rep. Matt Gaetz, R-Fla., has followed through on his renewed threat to introduce a motion to vacate against House Speaker Kevin McCarthy.

Gaetz, a frequent McCarthy critic, introduced the motion Monday evening on the House floor.

"Mr. Speaker, pursuant to clause 2A1 of Rule 9, I rise to give notice of my intent to raise a question of the privileges of House," Gaetz said. "Declaring the office Speaker of the House of Representatives to be vacant. Resolved that the office of Speaker of the House Representatives is hereby declared to be vacant."

Gaetz's move will force the House to take a vote on whether to keep McCarthy as speaker within two legislative days. 

There are a number of members undecided on how they would vote on such a measure, but it's likely McCarthy will need at least some Democrat votes to keep his job. Democrats could be in a position to try and extract concessions from McCarthy for their votes. 

Rep. Thomas Massie, R-Ky., told Fox News following Gaetz's move that he believes a motion to vacate at this time is "a bad idea." Additionally, Rep. Andy Ogles, R-Tenn., told Fox he was undecided.

McCarthy reacted to the motion with a post on X. "Bring it on," he simply said.

At a press gaggle follow the introduction of his motion, Gaetz said he had enough Republican votes to either oust McCarthy, or force him to appease Democrats for their support.

"I have enough Republicans where at this point next week, one of two things will happen: Kevin McCarthy won't be the Speaker of the House, or he'll be the Speaker of the House working at the pleasure of the Democrats. And I'm at peace with either results because the American people deserve to know who governs them," he said.
