 The man killed during the assassination attempt on former President Trump Saturday has been hailed as a hero. NPR's Meg Anderson reports Corey Comperator shielded his family when shots broke out at the rally. After their father died protecting them, Comperator's sister, Dawn Comperator Schaefer, wrote on Facebook that his two daughters are now living through the unthinkable. Comperator was a volunteer firefighter in Buffalo Township near Pittsburgh.
