The FBI is investigating what it said was another assassination attempt on Republican presidential candidate Donald Trump.
The incident occurred at the Trump International Golf Club West Palm Beach in Florida where the former president was golfing.
The suspect fled the bushes and was later apprehended on a highway, according to police.
In July, Mr Trump was shot by 20-year-old Thomas Crooks during a campaign rally in Pennsylvania in what the FBI said was an attempted assassination.
The former president was wounded in the ear.
The Congressional Research Service said direct assaults against presidents, presidents-elect and candidates have occurred on at least 15 separate occasions, with five resulting in death.
