Republican Mike Johnson narrowly won reelection Friday as House speaker on a first ballot, overcoming hard-right GOP holdouts in a tense standoff and buoyed by a nod of support from President-elect Donald Trump.

The House voted Friday to reelect Rep. Mike Johnson, R-La., after multiple Republicans initially did not cast a vote for him in what became a tight contest spurred by pushback from a small, but influential group of Republicans against the speaker, leading to President-elect Donald Trump getting involved in discussions.

The reversal leading to Johnson’s victory comes after President-elect Donald Trump endorsed Johnson and said he would make calls on Johnson’s behalf in the days leading up to the vote for a speaker, which must be completed before the House can conduct any further business.
