"I am pleased to inform you that Secretary of State Mike Pompeo is in the air and on his way back from North Korea with the 3 wonderful gentlemen that everyone is looking so forward to meeting. They seem to be in good health," Trump wrote in a post on Twitter.
Trump said he will greet Pompeo and the Americans when they land at Andrews Air Force Base outside Washington at 2 a.m. EDT (0600 GMT) Thursday morning. "Very exciting!" he wrote on Twitter.
