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

As Republicans met behind closed doors ahead of the speaker vote, it appeared Kevin McCarthy still did not have the votes needed to be elected.

Sources close to the Republican leader say he's ready to battle it out. It could go into multiple rounds of votes -- something that hasn't happened in 100 years -- and the floor fight could drag on for hours, if not days. The longest battle for speaker was in 1856, and it took two months and 133 votes to resolve.

Rep. Matt Gaetz, who opposes McCarthy's bid, has warned, "We may see the cherry blossoms bloom in Washington, D.C. before a speaker is elected."

All of this overshadows the start of the new Congress where Republicans have a majority in the House for the first time since 2018.

Rep. McCarthy has arrived for a closed-door meeting with his fellow Republicans.

"We are going to have a good day today," McCarthy said as he walked by reporters, who asked if he had the votes for speaker.

The California congressman then laughed as a reporter asked if he'd support Rep. Steve Scalise for speaker should he fail to get enough votes.

Hours before the vote to elect a new House speaker, a sign has appeared in front of the speaker's office with the message: "Follow Kevin McCarthy."

McCarthy was set to shore up more support for his speaker bid in a closed-door meeting with the Republican caucus this morning. He faces opposition from a group of hard-line conservatives, who could sink what is his second attempt to hold the gavel.

The California congressman's belongings have been brought into the speaker's suite, but if he doesn't get enough votes, he'll have to move out.

The House Republican conference will meet behind closed doors at 9:30 a.m., just hours before the speaker vote begins at noon.

While McCarthy might be able to garner more support in a last-ditch appeal, his detractors have boasted that they'll be able to muster the necessary opposition to block his bid.

Rep. Scott Perry, the chair of the House Freedom Caucus who is leading the group of hard-line conservatives opposing McCarthy's bid, released a new statement Tuesday morning blasting the California congressman.

"In his 14 years in Republican Leadership, McCarthy has repeatedly failed to demonstrate any desire to meaningfully change the status quo in Washington," Perry said.
