 This is Jonathan Sary in Bethel Park, Pennsylvania, outside the home of the gunman killed by Secret Service, Thomas Matthew Crooks. The shooting has led to much finger-pointing over whether the Secret Service perimeter at the rally was wide enough. Outside that perimeter, local police were handling security, and that included an area where the shooter fired from the rooftop of a building. Now, the Secret Service director says they'll fully participate in a national security review ordered by President Biden, who said in an Oval Office address last night.
