Former US president Donald Trump was the target of an 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 named Thomas Matthew Crooks, 20, of Bethel Park, Pennsylvania, as the subject involved in the assassination attempt. The agency said the investigation remains active and ongoing.

One attendee was killed and two spectators were critically injured, authorities said. All were identified as men. The Secret Service said it killed the suspected shooter — who it said attacked from an elevated position outside the rally venue, a farm show in Butler, Pennsylvania — and said Trump was safe.

The FBI said during a press conference late Saturday that they were not prepared to release the identity of the shooter and had not yet identified a motive for the assassination attempt.

Organizers said the convention would proceed as planned.
