Republicans end weeks of gridlock as US House elects new speaker Mike Johnson

Mike Johnson, a staunch ally of Donald Trump who spearheaded legal efforts to overturn the 2020 presidential election, received the unanimous support of his party to lead the lower chamber of Congress, which has been at a standstill since Kevin McCarthy was ousted in a right-wing coup on October 3.

The Louisiana congressman was the fourth Republican picked by his party in three weeks to replace Mr McCarthy, but the only nominee to garner enough support on the House floor, where he received several standing ovations from his colleagues.

“This House Republican majority is united,” Mr Johnson had told reporters as colleagues cheered and applauded following his nomination.

A virtual unknown, Mr Johnson’s lack of star power appears to have helped the 51-year-old lawyer and religious rights campaigner, who lacked the enemies from his own side that prompted the downfall of every other candidate.

Far from his party’s first choice, he was able to capitalise on the desperation of politicians to move on from the impasse, although winning the gavel was still a heavy lift in the deeply-fractured House Republican Conference.

“I haven’t heard one negative comment about him. Everybody likes him, he’s respected by all … somebody that’s going to be really spectacular and maybe for many years to come,” Mr Trump said ahead of the vote.

Formerly a junior member of the leadership as the conference vice chairman, Mr Johnson entered the House of Representatives in 2017, having stirred controversy with legislation seen as anti-gay in Louisiana state politics.

The married father of four also voted against codifying federal protections for same-sex marriage last year.

He was the ringleader among more than 100 Republicans who signed onto a legal brief supporting a lawsuit seeking to overturn the 2020 election results in four swing states won by President Joe Biden.

ABC News asked Mr Johnson late on Tuesday about the filing, which the Supreme Court declined to adjudicate, but he merely replied “next question” as his colleagues began jeering.

The son of a fireman and a conservative talk radio host, Mr Johnson was backed by House Majority Leader Steve Scalise and Judiciary Committee chairman Jim Jordan, who both fell short in their own speaker bids.

Failure by Mr Johnson would likely have plunged Republicans deeper into internecine conflict, with moderates beginning to look to Democrats for support with a consensus candidate —an extreme option that would be vehemently opposed by the hard-line right-wingers behind Mr McCarthy’s ouster on October 3.

Mr Johnson will be the least experienced speaker in the post Civil War era, having never chaired a committee or held a senior leadership role.

And he will almost immediately preside over a government shutdown that could threaten his job unless he can cut a 2024 budget deal favourable to his party with more seasoned negotiators such as Senate Majority Leader Chuck Schumer to Biden.

He will also be expected to lead his deeply fractured conference through upcoming fights over funding for Ukraine and Israel in their conflicts with Russia and Hamas.
