Trump's son, Donald Trump Jr., cited local law enforcement as saying an AK-47 automatic weapon had been discovered in bushes and a suspect has been apprehended, according to a post on X.
Reuters was not immediately able to confirm his account.
The Washington Post said Trump had been golfing at the course when the incident occurred. Secret Service agents took him to a holding room at the club, it said, citing two people briefed on what had happened.
