 From ABC News, I'm Chuck Sievertson. Former President Trump's chosen a former critic as his VP running mate, Ohio Senator J.D. Vance, in his second year of being a senator and at 39, a millennial. Hours ahead of Mr. Trump appearing at the convention opening night in Milwaukee, he spoke with ABC's Jonathan Karl. I asked Donald Trump if his close call with an assassin's bullet had changed him. He described his call with President Biden in the aftermath, telling me it was very nonexistent.
