 Saturday's attempted assassination of former President Donald Trump is still not known, but some details are coming out. CBS's Anna Schechter says local law enforcement, with direct knowledge of Saturday's shooting that left Trump with an ear injury, one attendee dead, and two others in critical condition, tell CBS News there were three municipal snipers inside the building that the shooter, 20-year-old Thomas Crooks of Bethel Park, Pennsylvania, was on. The operations plan had the sniper stationed inside the building, looking out windows toward the Trump rally.
