At a campaign rally near Butler, Pennsylvania, on July 13, 2024, Donald Trump was grazed in the upper right ear when Thomas Crooks fired eight rounds from a nearby rooftop with an AR-15-style rifle. Crooks killed attendee Corey Comperatore and critically wounded two others before return fire disrupted the attack and a Secret Service counter-sniper killed him seconds after it began. Images of Trump bloodied and raising his fist quickly became defining scenes of the 2024 campaign. The shooting led to intense scrutiny of rally security, the resignation of Secret Service director Kimberly Cheatle, and renewed debate over political violence and protective measures at later events.
