The Rise and Fall of Kevin McCarthy's Political Power

U.S. House Speaker Kevin McCarthy faces a challenge from hardline Republicans who accuse him of betraying an agreement that got him elected to lead the chamber, raising questions about the job security of the top Republican in Congress. About a dozen hardliners derailed a Republican effort in the House of Representatives on Tuesday to block new environmental regulations on household gas stoves, joining with Democrats to kill the measure in the Republican-controlled chamber. McCarthy oversees a narrow House Republican majority of 222-213, meaning that he can lose only four votes from his own party on any measure that faces uniform opposition from Democrats.
