Donald Trump's visit to the Trump International Golf Course Sunday, where gunman Ryan Wesley Routh allegedly attempted to assassinate the former President, was not supposed to happen, according to the Secret Service.
During a press conference Monday, United States Secret Service Acting Director Ronald Rowe revealed agents received little notice Trump planned to go golfing.
"This was an off-the-record movement," explained Rowe. "It wasn't a site that was on his schedule. It wasn't part of his schedule, so there was no posting up of it, because he wasn't supposed to have gone there in the first place."
"The President wasn't even really supposed to go there, it was not on his official schedule," Rowe reiterated. "And so we put together a security plan and that security plan worked."
Routh, 58, was charged in federal court earlier Monday with possession of a firearm by a convicted felon and possession of a firearm with an obliterated serial number, according to CBS News.
It's unclear if he entered a plea to the charges.
Routh was allegedly within 500 yards of Trump at the golf course, armed with an AK-47-style rifle when the Secret Service shot at him, the outlet reported, citing Palm Beach County Sheriff Ric Bradshaw.
Routh did not fire off any rounds.
He fled, but was subsequently arrested about 50 miles away soon after, allegedly with a rifle and scope in his vehicle.
Sunday's incident marks the second assassination attempt against Trump in just as many months. In July, Trump was grazed in the ear by a bullet during a campaign rally in Butler, Pennsylvania.
