Factbox-Who's in, who's out of the race to become US House speaker?

WASHINGTON (Reuters) - Republicans in the U.S. House of Representatives on Tuesday are holding closed-door votes as they try to pick a new speaker, with two members of the caucus left after several rounds of voting.

Here are the current candidates seeking to take the job that has been vacant since Oct. 3, bringing all legislative action in the House to a halt:

IN: TOM EMMER

Emmer, the House's No. 3 Republican and chief vote counter, has won the endorsement of former Speaker Kevin McCarthy, whose ouster by hardline party members set off the current crisis. A former ice hockey coach from Minnesota, Emmer said in a social media post on Saturday that he was running "to bring our conference together and get back to work."

IN: MIKE JOHNSON

Johnson, a conservative constitutional law attorney from Louisiana, has been a member since 2017. He said in a letter to colleagues on Saturday that he was running as a consensus candidate and billed himself as a "team player and a bridge-builder."

OUT: BYRON DONALDS

Donalds, a Republican from Florida and member of the hardline House Freedom Caucus, dropped out after four rounds of voting on Tuesday.

OUT: KEVIN HERN

Hern, from Oklahoma, is chair of the Republican Study Committee, a conservative policy group. He was eliminated in the fourth round of voting on Tuesday.

OUT: AUSTIN SCOTT

Scott is a Georgia lawmaker who has kept a relatively low profile in his 12 years in Congress. He was eliminated in a third round of voting on Tuesday.

OUT: JACK BERGMAN

Bergman, a retired Marine Corps lieutenant general who has been in Congress since 2017, was eliminated in a second round of voting on Tuesday.

OUT: PETE SESSIONS

Sessions was one of the more experienced candidates, having chaired the powerful House Rules Committee and headed the House Republican's campaign arm. He was eliminated in the first round of voting on Tuesday.

OUT: GARY PALMER

Palmer, an outspoken defender of former President Donald Trump, was elected to Congress in 2014. The chair of the House Republican Policy Committee, whose goal is to unite congressional Republicans, dropped out on Tuesday.
