According to Federal prosecutors, accused Ryan Wesley Routh, 58, set up a sniper's nest on the outer perimeter of Trump International West Palm Beach and remained there for about 12 hours, NY POST reported.

Speaking to the reporters on Monday, Acting Secret Service Director Ronald Rowe Jr. defended the agency's security measures in place, stating that officials didn't conduct a thorough inspection of the perimeter since Trump's trip wasn't on his official schedule.

“The president wasn’t even really supposed to go there. It was not on his official schedule,” he stated.

In reference to Routh's detention, he explained, “And so we put together a security plan — and that security plan worked.”

Rowe did not elaborate if the “off-the-record” stop meant that agents were unable to thoroughly search Trump's golf property in the time allotted.

Nevertheless, the acting director applauded the agents who eventually managed to see the barrel of an AK-style rifle poking through the course's foliage and opened fire on the individual in question before he could do so.

Secret Service under intense scrutiny

A criminal complaint claims that the suspect abandoned his rifle, two backpacks, and a GoPro camera before fleeing in an SUV after an agent opened fire.

Authorities reported that Routh was detained on Interstate 95 around forty minutes after the incident.

Rowe's statement comes at a time when the Secret Service is facing intense scrutiny following the first attempt on Trump's life on July 13 at a campaign rally in Butler, Pennsylvania.
