 We're learning more about the shooter in that assassination attempt on former President Trump from the rally over the weekend in Pennsylvania. Correspondent Clayton Neville has that part of the story. The shooter identified as 20-year-old Thomas Matthew Crooks of Bethel Park, Pennsylvania. He was in muted colors, tan, tight clothing. We saw the rifle flinging around as he was trying to crawl. Witnesses told the BBC that they saw Crooks before the shooting and told police.
