President-elect Donald Trump endorsed Rep. Mike Johnson for Speaker of the House ahead of a key vote as the 119th Congress convenes. Trump expressed his support on social media, emphasizing that Johnson is a capable leader and urging Republicans to unite behind him. With the GOP’s slim majority in the House, Johnson requires nearly full backing from Republican members to secure the position. Any dissent could jeopardize his election, especially with Rep. Thomas Massie publicly opposing him. Johnson, first elected speaker on October 25, 2023, succeeded Kevin McCarthy following his ousting. The vote is expected before 1 p.m. ET.
