The 119th Congress convenes Friday at noon with a critical vote for House Speaker on the line. With a slim Republican majority in the House, Speaker Mike Johnson, who wants to keep the role, will need nearly all members of his party to vote for him. The House remains paralyzed until the election of a speaker. Republicans, who will have majority control in the House, Senate, and White House, remain eager to implement President-elect Donald Trump's "America First" agenda."American families are ready to see agenda," Johnson said in a press conference last month. "We got to take care of the border as a top priority, and we will. We got to get the economy going again, and we will. We're going to achieve these objectives, and we're going to get it done."In the Senate, Republicans are aiming to quickly confirm Trump's nominees to his administration."Republicans are united around making sure President Trump's nominees are put in place and ready to roll up their sleeves and go to work," Senate Majority Leader John Thune, R-South Dakota, said.But Republican leaders and their ability to follow through on plans will depend largely on balancing demands between moderates and conservatives. On Friday, House Republicans will face their first true test of putting aside their differences with the speakership vote."I think it's a bit of an integrity problem when you say right before the vote, you suddenly get cold feet," Rep. Don Bacon, R-Nebraska, said. "It hurts the conference. It hurts the House. It hurts President Trump by them doing this, and they're really putting themselves over the team."Democrats may also plan to use Republicans' slim majority in both chambers to leverage their own agenda."We will seek to find common ground with the incoming administration," House Minority Leader Hakeem Jeffries, D-New York, said. "It's clear that the incoming House Republican majority will not be able to do much without us."Trump endorsed Johnson for speaker in a social media post last month, but his support does not guarantee enough far-right Republicans will elect him to the job. Electing a House Speaker can be a timely process. Lawmakers will call out the name of their choice for speaker one by one. Anyone can be nominated.Candidates need a majority vote from House lawmakers who are present. Failure to reach a majority threshold could spark multiple rounds of voting.So far, a handful of Republicans have either said they do not plan to vote for Johnson, are undecided, or won't publicly say ahead who they will choose. Johnson can afford to lose two votes.
