 Good morning. Ohio U.S. Senator J.D. Vance once described former President Trump using words like idiot and Hitler. Now he says he's a convert and joins Trump on the ticket at the Republican convention. It's Morning Edition from NPR News. It's 7 o'clock and mostly sunny. Good deal of sunshine today and very high temperatures, too. Could be an afternoon shower. On the convention's first day, Republicans adopted a platform. I'm Sasha Pfeiffer.
