FBI officials said on Sunday they were assessing the shooting of Donald Trump at a campaign rally on Saturday as a possible domestic terrorism attack and assassination attempt, as federal investigators executed a flurry of warrants in trying to determine a motive.
The officials said there was no evidence that the 20-year-old suspected gunman, identified as Thomas Matthew Crooks from Bethel Park, Pennsylvania, was operating as part of a larger group. But his reasons for scaling the roof of a building overlooking the rally to shoot at Trump remained unclear.
