As the new Congress opens, Speaker Mike Johnson's leadership is tenuous, facing opposition from GOP hardliners and uncertainty over his ability to secure votes. With a slim 219-215 Republican majority, Johnson can only afford one defection. Critics, including Rep. Thomas Massie, have publicly opposed him, while demands from conservatives for concessions complicate matters. Johnson struggles despite Trump's endorsement, as Democrats aim to unify against him for House Minority Leader Hakeem Jeffries, further increasing the stakes ahead of the pivotal Jan. 6 electoral certification.
