 This is a special report from ABC News, Trump assassination attempt. I'm Mark Remillard. The FBI identifying the gunman, they say, opened fire at a rally for former President Trump on Saturday, wounding Trump in the ear. Bullets whizzed past the former president as federal authorities say 20-year-old Thomas Matthew Crooks opened fire from a rooftop a few hundred yards outside the venue in Pennsylvania where Trump was speaking at the time. FBI Special Agent in Charge Kevin Rojack providing an update late Saturday.
