 At the Republican National Convention, security remains heightened following the assassination attempt of Donald Trump in Pennsylvania. Trump last night announcing his choice for vice president, Senator J.D. Vance of Ohio. ABC's Terry Moran is in Milwaukee and says Vance has come full circle from a one-time Trump critic. He was as fiercely anti-Trump as you could get back in 2016 when I interviewed him and then sat next to him in ABC's coverage. He was an ABC consultant and he hated Trump.
