President-elect Donald Trump has nominated billionaire investment banker Warren Stephens to serve as the U.S. ambassador to the UK. The announcement was made on Trump's Truth Social platform and requires Senate confirmation. Stephens, a prominent Republican donor who contributed $2 million to a Trump-supporting super PAC, is set to strengthen U.S.-UK relations. The nomination also brought disappointment among New York Jets fans hoping for the return of team owner Woody Johnson to the ambassador role after his previous term. Trump has been making selections from a roster of loyal supporters for key positions.
