🔰Trump backs House Speaker Mike Johnson amid Republican infighting

Tonight, President-elect Donald Trump is hoping to avoid a showdown within his own party. He's now fully endorsing Speaker Mike Johnson for another term ahead of a vote in the House this week. But Johnson still may not have enough support. Republicans with a razor-thin margin. And the stakes are high. Without a speaker, the House would likely be unable to certify Trump's victory. Here's ABC's Mary Alice Parks. Tonight President-elect Donald Trump throwing his support behind Speaker of the House Mike Johnson, saying Johnson has his complete and total endorsement in his fight to keep the gavel. Speaker Mike Johnson is a good, hard-working religious man, Trump wrote on social media, urging fellow Republicans to get in line, writing, let's not blow this great opportunity which we've been given. Johnson has been facing pushback from the far right for weeks. Earlier this month, Trump ally Steve Bannon blasting the speaker for his willingness to work with Democrats to pass a spending bill. Johnson's not up to the task, he's got to go, right? He's got to go. Should Johnson be Speaker of the House? The vote is going to be close. Speaker Johnson can likely only afford to lose one Republican. And the stakes could not be higher for the incoming administration. The House will be at a standstill, likely unable to even certify Trump's election until a speaker is chosen. Now it's unclear whether Trump's endorsement will sway those fiscal hawks who've been angry at Johnson, but the speaker was still grateful for the support, writing on X that he's ready to deliver on Trump's America First agenda. Mary? A critical test for the speaker and the incoming president. Mary Alice, thank you.
