 On the Hour, sponsored by O'Reilly Auto Parts. I'm Stacy Lynn. We're learning more about the shooter who opened fire at a Trump rally yesterday. 20-year-old Thomas Crook was from Bethel Park, Pennsylvania. Jason Kohler is a former classmate of his. I didn't have any interaction with him, but he was like a kid that was always alone. He was always bullied every day. He was just an outcast.
