 NCI News. I'm Mike Raley. Federal investigators are trying to figure out why a would-be assassin attempted to take the life of former President Trump at a rally in Pennsylvania. One bystander was killed, two critically injured. Shooter is identified as a 20-year-old from a town one hour north of the rally's location. CBS's Meg Oliver has the latest from western Pennsylvania. Suspicious devices were also found in the gunman's vehicle, and a device that appeared capable of triggering the devices was found in the gunman's possession.
