'Caucus is unified': McCarthy's Jan. 6 actions cited as Democrats seem poised to doom speaker

House speaker Kevin McCarthy (R-CA) is starting to look like he won't survive a challenge to his leadership.

Rep. Matt Gaetz (R-FL) has filed a motion to vacate, which McCarthy has said he plans to bring up for a vote Tuesday afternoon. And Democrats have said they will not vote present or vote in favor of tabling the motion -- which could doom the California Republican.

"Sources say the caucus is unified," reported the Washington Post's Leigh Ann Caldwell. "McCarthy’s actions on Jan 6, his trip to Mar a Lago, his attempt to discredit the Jan 6 Cmte, his reneging on debt limit deal and his actions this weekend are all the reasons."

House minority leader Hakeem Jeffries (D-NY) has actively urged Democrats to vote against any procedural motion to delay the vote on Gaetz's measure, and he believes Democrats should vote to remove McCarthy as speaker after less than a year on the job.

Four Republican lawmakers have publicly committed to voting to oust McCarthy, and a handful of others say they're leaning in that direction.

McCarthy can only afford to lose five GOP votes if Democrats stand united against him.
