President Donald Trump announced former national security advisor Mike Waltz as his choice to serve as ambassador to the U.N. after Rep. Elise Stefanik withdrew her nomination amid concern over the GOP's slim majority in the House.

President Trump removed Mike Waltz as national security adviser because the Floridian would be a “better UN ambassador,” Vice President JD Vance said Thursday — arguing that the former congressman’s nomination to rep the US in Turtle Bay could be considered a “promotion.”

National security adviser Mike Waltz and his deputy, Alex Wong, will be leaving their posts in the Trump White House, according to multiple sources familiar with their departure.
