Donald Trump was shot in the ear during a Saturday campaign rally, in an attack that left the Republican presidential candidate's face streaked with blood and prompted his security agents to swarm him, before he emerged and pumped his fist in the air, mouthing the words "Fight! Fight! Fight!"
The shooter was dead, one rally attendee was killed and two other spectators were injured, the Secret Service said in a statement. The incident is being investigated as an assassination attempt.
Law enforcement officials told reporters they had tentatively identified a suspected shooter but were not ready to do so publicly. They also said they not yet identified a motive.
Trump, 78, had just started his speech when the shots rang out. He grabbed his right ear with his right hand, then brought his hand down to look at it before dropping to his knees behind the podium before Secret Service agents swarmed and covered him. He emerged about a minute later, his red 'Make America Great Again' hat knocked off, and could be heard saying "wait, wait," before the fist bump, then agents rushed him to a black SUV.
"I was shot with a bullet that pierced the upper part of my right ear," Trump said later on his Truth Social platform following the shooting in Butler, Pennsylvania, about 30 miles (50 km) north of Pittsburgh. "Much bleeding took place."
The shooting occurred less than four months before the November 5 election. Leading Republicans and Democrats quickly condemned the violence. The Trump campaign said he was "doing well". President Biden said in a statement: "There’s no place for this kind of violence in America. We must unite as one nation to condemn it."
The shooting raised immediate questions about security failures by the Secret Service, which provides former presidents including Trump with lifetime protection.
It was the first shooting of a US president or major party candidate since the 1981 attempted assassination of Republican President Ronald Reagan.
