Secret Service Did Not Search Trump Golf Course Perimeter Before Gunman’s Arrest

The Secret Service did not search the perimeter of the Trump International Golf Club in West Palm Beach, Fla., on Sunday before former President Donald J. Trump began his round, an acknowledgment that has put the besieged agency under renewed scrutiny two months after a similar episode in Pennsylvania.

The decision raises further questions about whether the Secret Service has the resources and ability to adequately perform its duties during a time of increasing violence and a unique campaign between a sitting vice president and a former president.

While the agency’s acting director hailed a Secret Service agent for acting swiftly and preventing any harm to Mr. Trump on Sunday, the F.B.I. said that data from a gunman’s cellphone indicated he spent almost 12 hours near the course before he aimed a rifle in the direction of Mr. Trump while he was golfing.

In remarks to reporters at the Palm Beach County Sheriff’s Office on Monday afternoon, Ronald L. Rowe Jr., the Secret Service’s acting director, said, “The president wasn’t even really supposed to go there.”

Mr. Rowe said Mr. Trump, the Republican presidential nominee, did not have an outing on the course on his official schedule. Mr. Rowe did not clarify in his statements whether this meant that agents did not have time to sweep the golf course. Yet it is public knowledge that Mr. Trump frequently plays golf at one of his Florida courses on Sundays, raising the risk level for the former president.

Mr. Rowe praised his agents for spotting the barrel of a gun poking through the bushes of the golf club and firing at the suspect, Ryan W. Routh, 58, before he could get off a shot. A manhunt commenced, leading to Mr. Routh being detained soon after. He was charged in federal court on Monday with possession of a firearm as a felon.
