The FBI has identified Thomas Matthew Crooks, a 20-year-old man from western Pennsylvania, as the person who attempted to assassinate former President Trump at a campaign event in Butler, Pennsylvania, on Saturday.

Crooks reportedly shot Trump from a rooftop perch some 130 yards away during a rally in the small town, striking the upper part of Trump’s right ear while the former president was speaking to rallygoers ahead of next week’s Republican National Convention in Milwaukee.
