U.S. President-elect Donald Trump nominated retired Gen. Keith Kellogg as his special envoy for Ukraine and Russia, choosing a longtime adviser who’s supported his aims to end the war swiftly, including by potentially cutting off military aid to Kyiv.

Trump, a longtime skeptic of continued U.S. assistance to Ukraine, has vowed to settle its conflict with Russia before even taking office. In writings over the last year, Kellogg has proposed a path forward that offers an indication of how Trump might try to fulfill that promise.

"Keith has led a distinguished Military and Business career, including serving in highly sensitive National Security roles in my first Administration,” Trump said in a post to his Truth Social account on Wednesday. "He was with me right from the beginning! Together, we will secure PEACE THROUGH STRENGTH, and Make America, and the World, SAFE AGAIN!”
