Live updates: FBI says motive in Trump rally shooting is unknown; Biden to give Oval Office speech tonight

An FBI official said the investigation into the gunman at Donald Trump’s rally Saturday has not yet turned up any mental health issues, threatening posts or other motives, but cautioned it was still early. The bureau identified the shooter, who is dead, as 20-year-old Thomas Matthew Crooks of Bethel Park, Pa. Pennsylvania Gov. Josh Shapiro (D) identified the person killed during the rally as Corey Comperatore, 50, saying he died “protecting his family.” Trump on Sunday urged Americans to “stand united” after the shooting and said he was “shot with a bullet that pierced the upper part of my right ear.”
