President Donald Trump went after British Prime Minister Keir Starmer over his decision to appoint a U.S. ambassador who was later fired following revelations about the envoy's ties to Jeffrey Epstein. "Prime Minister Keir Starmer of the United Kingdom acknowledged that he 'exercised wrong judgement' when he chose his Ambassador to Washington," Trump wrote on Truth Social, referring to former ambassador Peter Mandelson. "I agree, he was a really bad pick," the president added.
