BUTLER, Pa. (AP) — Former President Donald Trump was the target of an apparent assassination attempt Saturday at a Pennsylvania rally, days before he was to accept the Republican nomination for a third time. A barrage of gunfire set off panic, and a bloodied Trump, who said he was shot in the ear, was surrounded by Secret Service and hurried to his SUV as he pumped his fist in a show of defiance.

Trump’s campaign said the presumptive GOP nominee was doing “fine” after the shooting, which he said pierced the upper part of his right ear.

“I knew immediately that something was wrong in that I heard a whizzing sound, shots, and immediately felt the bullet ripping through the skin. Much bleeding took place,” he wrote on his social media site.

The FBI early Sunday identified the shooter as Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania. The agency said the investigation remains active and ongoing.

Secret Service agents fatally shot Crooks, who attacked from an elevated position outside the rally venue at a farm show in Butler, Pennsylvania, the agency said.

One attendee was killed and two spectators were critically injured, authorities said. All were identified as men.
