New Congress live updates: What's next after Kevin McCarthy's speakership win

Rep. Marjorie Taylor Greene, R-Ga., a member of the House Freedom Caucus who has broken with some colleagues and supports Kevin McCarthy's bid for speaker, blasted colleagues for opposing him.

"This is not anything about the country. This is all about 'Never Kevin,' they just don't like Kevin McCarthy, and you cannot be successful in anything if you aren't able to walk in a room, make what you want, and get a deal done, and then walk away with a W," Greene said.

"This is not about prom king, this is not about a pastor. This about electing a person to sit in the speaker's chair so we can get to work."

Greene also praised the new House GOP rules package.

At least three House Republicans likened the closed-door GOP conference meeting, which lasted over an hour, to tense infighting that did not persuade them to vote for Kevin McCarthy as House speaker.

"Kevin McCarthy was taking the path of Nancy Pelosi and following her precedent with a motion to vacate," said Rep. Lauren Boebert, R-Colo., who just narrowly won he reelection to the House. "I will not be voting for Kevin McCarthy."

Rep. Scott Perry, R-Penn., speaking alongside Rep. Matt Gaetz, R-Fla., said McCarthy would only get his vote if "something dramatic changes."

"If you vote for somebody else in the first ballot, and nothing changes on the second or third or whatever, what's going to compel you to change?" Perry told reporters.

"This meeting wasn't about trying to inform people about what it takes to get to 218 and ask what you want," he added. "This was about a beatdown and a simulated unity in the room, which really doesn't exist."

Emerging from the closed-door GOP conference meeting, Rep. Matt Gaetz said nothing McCarthy said was enough to get his support.

"Everything I heard hardened my resolve that this town desperately needs change, and if it's a few of us who have to stand in the breach to force it, we are willing to do so for as long as it takes," Gaetz said.

Gaetz said he will vote for Rep. Andy Biggs of Arizona to become speaker, arguing McCarthy hasn't done enough to bring change.

"There's very little difference between Nancy Pelosi and her California delegation-mate that seeks the gavel," Gaetz said. "We want to change because this town is broken. And this is a person who has acknowledged, Mr. McCarthy, that the town is broken and he has been a part of that process for many years as a member of the leadership."

In a closed-door meeting with House Republicans, Kevin McCarthy made a last-ditch case for speaker.

"I'm not going to go away. I'm going to stand until the last four friends stand with me," he told the GOP members, according to a source in the room.

"I earned this job," McCarthy said. "We earned this majority, and goddammit we are going to win it today."

Sources said he received a standing ovation from most members in the room, but it may not have been enough to win over Republicans who are on the fence. Other sources indicated that conservative members were "livid" at McCarthy's response.
