President-elect Donald Trump threw his support behind Speaker Mike Johnson (R-LA) for a second term in the top House leadership position, hoping to quash opposition as a growing number of Republican lawmakers consider alternative candidates.

In a lengthy statement posted to Truth Social on Monday, Trump urged Republicans not to “blow this great opportunity” to advance the party’s agenda after winning both chambers of Congress and the White House, arguing Johnson is a strong leader to achieve that in the House. Trump’s endorsement comes amid a growing number of House Republicans expressing dissatisfaction with Johnson over his handling of the government spending deal earlier this month, with some even threatening to vote against his speakership bid on Jan. 3.
