House Republican Vice Chair Rep. Mike Johnson (R-La.) became the chamber’s Speaker on Wednesday, three weeks after Speaker Kevin McCarthy was ousted. On Tuesday, Johnson became his conference’s fourth nominee to replace McCarthy, and he takes over in the midst of multiple international crises, most notably in Israel, Gaza and Ukraine. There has been a split in the House GOP over aid to Ukraine for its war against Russia, making the passage of some recent bills a tough hill to climb in the lower chamber.
