 Vance is 39 years old and was endorsed by Trump when he ran for office two years ago. He learned he was the choice only 20 minutes before Trump announced it with the 2,400 convention delegates later making the Trump-Vance ticket official. Trump's damaged ear is covered by a bandage, a reminder of Saturday's close call with a sniper in Pennsylvania. CBS News correspondent Scott McFarlane is following the investigation into the shootings.
