WASHINGTON (AP) — The man who authorities say pointed a rifle with a scope into former President Donald Trump’s golf club and was arrested is Ryan Wesley Routh, three law enforcement officials told The Associated Press.

The officials identified the suspect to the AP but spoke on the condition of anonymity because they were not authorized to discuss the ongoing investigation.

Secret Service agents shot at the suspect, who was taken into custody after fleeing the scene of what the FBI is calling an apparent attempted assassination of the Republican presidential nominee. Authorities are working to determine a motive.

The FBI said Donald Trump was the target of “what appears to be an attempted assassination” at his golf club in West Palm Beach, Florida, on Sunday, just nine weeks after the Republican presidential nominee survived another attempt on his life. The former president said he was safe and well.

Palm Beach County Sheriff Ric Bradshaw said the U.S. Secret Service agents fired at a man pointing an AK-style rifle with a scope as Trump was on the course. Bradshaw said the gunman also had two backpacks hanging on a fence and a GoPro camera, and that he was about 400 yards to 500 yards away from Trump and hiding in shrubbery while the former president played golf on a nearby hole. The person dropped the weapon and fled in an SUV, and was later taken into custody in a neighboring county.

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.

In an email to supporters, Trump said: “There were gunshots in my vicinity, but before rumors start spiraling out of control, I wanted you to hear this first: I AM SAFE AND WELL!”

“Nothing will slow me down. I will NEVER SURRENDER!” he said.

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, Bradshaw 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.

He 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 Sunday 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.

Snyder said his deputies “immediately flooded” northbound I-95, deploying to every exit between the Palm Beach County line to the south and St. Lucie County line o the north.

“One of my road patrol units saw the vehicle, matched the tag and we set up on the vehicle,” Snyder said, “We pinched in on the car, got it safely stopped and got the driver in custody.”

Snyder told WPTV that the suspect “was not armed when we took him out of the car.”

The man had a calm, flat demeanor and showed little emotion when he was stopped by police, Snyder said, saying the suspect did not question why he was being pulled over.

“He never asked, ‘what is this about?’ Obviously, law enforcement with long rifles, blue lights, a lot going on. He never questioned it,” Snyder said.

Attorney General Merrick Garland has been briefed on the situation and is receiving regular updates about it, a Justice Department spokeswoman said.

The post by the Martin County Sheriff’s Office indicated the suspect was apprehended near Palm City, Florida, about a 45-mile drive north of Trump’s golf course. Northbound lanes of I-95 were shut down, the sheriff’s office said.

A message sent to campaign officials seeking information on the security status and location of Ohio Sen. JD Vance, Trump’s running mate, was not immediately returned.

Max Egusquiza, of Palm Beach, described the emergency response outside Trump’s West Palm Beach golf course.

“From what I saw 5 black unmarked SUVs blocked in a grey Mercedes in front of the golf course. There were about 20 or more cop cars flying from nearby streets,” he said.

Trump is supposed to speak about cryptocurrency live Monday night on the social media site X for the launch of his sons’ crypto platform. He’s expected to do that from his Mar-a-Lago resort in Florida. The former president is scheduled to return to the campaign trail on Tuesday for a town hall in Flint, Michigan with his former press secretary, Arkansas Governor Sarah Huckabee Sanders, followed by a campaign rally in New York on Long Island on Wednesday.

At the end of the week, he’s scheduled to attend and address the Israeli-American Council National Summit in Washington, D.C. and on Saturday hold a rally in Wilmington, North Carolina.
