What happened to Trump on Sunday?
Authorities said a man stuck the barrel of a rifle through the fence at the edge of the golf course while the former president was golfing. Secret Service agents on the course spotted the weapon and opened fire on the man, who fled.
Authorities later said they identified the vehicle, a black Nissan, thanks to a bystander's photograph, and soon traced it to neighboring Martin County to the north. David Aronberg, state attorney for Palm Beach County, confirmed to USA TODAY that the suspect in custody is Routh.

David Aronberg, state attorney for Palm Beach County, confirmed to USA TODAY that the suspect in custody is Ryan Routh , 58. He said his prosecutors were preparing an arrest warrant and pretrial detention for Routh when federal prosecutors told him they were taking over the case, so he backed off.
Aronberg also said an AK-47 rifle believed to belong to Routh was recovered at the scene. Aronberg said Routh appeared to be at least partly motivated by his strong support for Ukraine and its war against Russia. “He’s someone who obviously has some issues,” he said. "Normal people don’t commit crimes like this."
Public records indicate a man of that age named Ryan Routh lived in Hawaii, but voting records showed the same man as a longtime voter in North Carolina. State voting records show him casting ballots in general and municipal elections going back many cycles, including 2008 and 2012 − though not in 2016, when Trump first ran.
The same records show Routh voted most recently in the March primary election this year in Guilford County, North Carolina. A registered Democrat, he voted in person.
