Republicans were deadlocked on Tuesday over who would lead their new majority after Representative Kevin McCarthy of California lost three votes for the top job, as hard-right lawmakers in open revolt dealt their party leader a humiliating setback and prompted a historic struggle on the House floor.
The mutiny, waged by ultraconservative lawmakers who for weeks have held fast to their vow to oppose Mr. McCarthy, paralyzed the House on the first day of Republican rule, delaying the swearing in of hundreds of members of Congress, putting off any legislative work and exposing deep divisions that threaten to make the party’s House majority ungovernable.
