Donald Trump was shot in the ear in an attempted assassination during a campaign rally on Saturday, an attack that will likely reshape this year’s US presidential race while raising sharp questions about security provided to the Republican candidate.

In the moments after the shooting, Trump was swarmed and covered up by his security agents. He quickly emerged from the scrum, his face streaked with blood, and pumped his fist in the air, mouthing the words “Fight! Fight! Fight!”

The Trump campaign later said he was “doing well” and appeared to have suffered no major injury besides a wound on his upper right ear.

Early on Sunday the FBI identified 20-year-old Thomas Matthew Crooks of Bethel Park, Pennsylvania, as the “subject involved” in what it termed an attempted assassination. He was a registered Republican, according to state voter records.

The suspect was shot dead by Secret Service agents, the agency said, after he opened fire from the roof of a building about 140 metres from the stage where Trump was speaking. An AR-15-style semiautomatic rifle was recovered near his body.

One person who attended the rally was killed and two other spectators were critically wounded, the Secret Service said.

Law enforcement officials told reporters they had not yet identified a motive for the attack.

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 covered him.

He emerged about a minute later, his red “Make America Great Again” hat knocked off. He could be heard saying “wait, wait,” before pumping his fist in the air. Agents then 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.”

Trump left the Butler area under Secret Service protection and later arrived at his golf club in Bedminster, New Jersey.

The attack was the first shooting of a US president or major party candidate since the 1981 attempted assassination of Republican President Ronald Reagan.

It raised immediate questions about security failures by the Secret Service, which provides former presidents including Trump with lifetime protection. The FBI said it had taken the lead in investigating the attack.

The shooting occurred less than four months before the Nov 5 election, when Trump faces an election rematch with Democratic President Joe Biden. Most opinion polls including those by Reuters/Ipsos show the two locked in a close contest.

Investors said that the attack and Trump’s defiant response would likely increase his chances of winning back the White House, and trades betting on his victory will increase this coming week.

Trump is due to receive his party’s formal nomination at the Republican National Convention, which kicks off in Milwaukee on Monday.

Four shots and the crowd ducks

Ron Moose, a Trump supporter at the rally, said he heard about four shots. “I saw the crowd go down and then Trump ducked, also real quick,” he said. “Then the Secret Service all jumped and protected him as soon as they could. We are talking within a second they were all protecting him.”

The BBC interviewed a man who said he saw a man armed with a rifle crawling up a roof near the event. The self-described eyewitness, who the BBC did not identify, said he and the people he was with started pointing at the man, trying to alert security.

The shots appeared to come from outside the area secured by the Secret Service, the agency said.

At a briefing late on Saturday, FBI officials told reporters it was surprising that the suspect was able to fire multiple shots. The Secret Service did not have a representative at that briefing.

Hours after the attack, the Oversight Committee in the Republican-led US House of Representatives summoned US Secret Service Director Kimberly Cheatle to testify at a hearing scheduled for July 22.

“Americans demand answers about the assassination attempt of President Trump,” the panel said in a statement on social media.

Trump supporters blasted the Secret Service.

“How was a sniper with a full rifle kit allowed to bear crawl onto the closest roof to a presidential nominee,” asked conservative activist Jack Posobiec on social media site X.

Republicans, Democrats decry violence

Leading Republicans and Democrats quickly condemned the violence, as did foreign leaders. “There’s no place for this kind of violence in America. We must unite as one nation to condemn it,” Biden said in a statement.

Biden’s campaign was pausing its television ads and halting all other outbound communication, a campaign official said.

The attack heightened longstanding worries that political violence could erupt during the presidential campaign and after the election. The concerns in part reflect the electorate’s polarization, with the country appearing bitterly divided into two camps with divergent political and social visions.

“This horrific act of political violence at a peaceful campaign rally has no place in this country and should be unanimously and forcefully condemned,” Republican House Speaker Mike Johnson said on social media.

Democratic Senate Majority Leader Chuck Schumer said he was horrified by what happened and was relieved Trump was safe. “Political violence has no place in our country,” he said.

Americans fear rising political violence, recent Reuters/Ipsos polling shows, with two out of three respondents to a May survey saying they worried violence could follow the election.

Some of Trump’s Republican allies said they believed the attack was politically motivated.

“For weeks Democrat leaders have been fueling ludicrous hysteria that Donald Trump winning re-election would be the end of democracy in America,” said US Representative Steve Scalise, the No 2 House Republican, who survived a politically motivated shooting in 2017.

“Clearly we’ve seen far left lunatics act on violent rhetoric in the past. This incendiary rhetoric must stop.”

Trump, who served as president from 2017-2021, easily bested his rivals for the Republican nomination early in the campaign. He unified his party around him after its support wavered briefly when his supporters attacked the US Capitol on Jan 6, 2021, attempting to overturn his 2020 election defeat.

The businessman and former reality television star entered the year facing a raft of legal worries, including four separate criminal prosecutions.

He was found guilty in late May of trying to cover up hush money payments to a porn star. But the other three prosecutions he faces – including two for his attempts to overturn his defeat – have been ground to a halt by various factors, including a Supreme Court decision early this month that found him to be partly immune to prosecution.

Trump contends, without giving evidence, that all four prosecutions have been orchestrated by Biden to try to prevent him from returning to power.
