A man with an AK–style rifle pointed the firearm’s muzzle into Donald Trump’s golf club in West Palm Beach, Florida, as the former president was playing a round, prompting the U.S. Secret Service to open fire, according to three law enforcement officials. The former president is safe and unharmed, and the FBI says it is investigating “what appears to be an attempted assassination” of the Republican presidential candidate.

The person dropped the weapon and fled in an SUV, and was later taken into custody in a neighboring county, the officials said. The officials were not authorized to discuss the ongoing investigation and spoke to The Associated Press on condition of anonymity.

An AK–style firearm was recovered at the scene near Trump International Golf Club West Palm Beach, two of the officials said. And no injuries were reported.

The incident was the latest jarring moment in a campaign year marked by unprecedented upheaval. It occurred roughly two months after Trump was shot during an assassination attempt at a rally in Pennsylvania, and a bullet grazed his ear. Only a week later, President Joe Biden withdrew from the race.

The golf course was partially shut down for Trump as he played, and agents were a few holes ahead of him when they noticed the person with the firearm, the officials said. There are several areas around the perimeter of the property where golfers are visible from the fence line. Secret Service agents and officers in golf carts and on ATVs generally secure the area several holes ahead and behind Trump when he golfs. Agents also usually bring an armored vehicle onto the course to quickly shelter Trump should a threat arise.

Trump had returned to Florida this weekend from a West Coast swing that included a Friday night rally in Las Vegas and a Utah fundraiser. His campaign had not advised Trump’s plans for Sunday. He often spends the morning playing golf, before having lunch at the club, one of three he owns in the state.

The former president has had a stepped–up security footprint since the assassination attempt in July. When he has been at Trump Tower in New York, a lineup of dump trucks have parked in a wall outside the building. And at outdoor rallies, he now speaks from behind an enclosure of bulletproof glass.

Trump was returned safely after the incident to his private Mar–a–Lago club, where he resides in neighboring Palm Beach, according to a person familiar with the matter.

The White House said President Joe Biden and Vice President Kamala Harris, the Democratic presidential nominee, had both been briefed and would be kept updated on the investigation. The White House added they were “relieved” to know Trump is safe.

Harris, in a statement said she was “glad” Trump was safe, adding that “violence has no place in America.”

In an X post, Sen. Lindsey Graham, R–S.C, one of Trump’s top congressional allies, said he had spoken with Trump after the incident and that Trump was in “good spirits” and was “one of the strongest people I’ve ever known.”

Martin County Sheriff William D. Snyder said the suspect was apprehended within minutes of the FBI, Secret Service and Palm Beach County Sheriff’s Office putting out a “very urgent BOLO” — or “be on the lookout” alert” detailing the specific vehicle sought, license plate number and occupant description.
