President-elect Donald Trump has nominated Rep. Elise Stefanik as the next U.S. ambassador to the United Nations. Known for her strong backing of Trump and Israel, she plans to push for increased funding contributions from allies and reassess U.S. funding to the UN. Stefanik's vacancy in the House has prompted several GOP lawmakers, including Lisa McClain and Kat Cammack, to enter the race for her current leadership position. The Senate, now controlled by Republicans, is expected to confirm her nomination, signaling a significant shift within GOP leadership dynamics.
