Donald Trump says he has chosen former acting Attorney General Matt Whitaker to serve as U.S. ambassador to NATO, the bedrock Western alliance that the president-elect has repeatedly expressed skepticism about.

Trump, in a statement, said Whitaker was “a strong warrior and loyal Patriot” who “will ensure the United States’ interests are advanced and defended” and “strengthen relationships with our NATO Allies, and stand firm in the face of threats to Peace and Stability.”
