Republicans have chosen Rep. Mike Johnson of Louisiana as their latest nominee for House speaker. This comes hours after another Republican nominee, Rep. Tom Emmer, abruptly withdrew his bid amid opposition from Donald Trump. Johnson is the fourth candidate Republicans have now nominated to replace Kevin McCarthy, who was ousted three weeks ago. Republicans are desperate to end the chaos and get back to work. Johnson had been the second-place vote getter in a morning round of voting. But it's unclear if any Republican nominee can unite the party's hardline and more traditional factions to win the gavel in a floor vote.
