The US Secret Service found a “suspicious” hunting stand within sight of the Air Force One landing zone ahead of the president’s arrival in Florida over the weekend, FBI Director Kash Patel said, adding no one was at the stand.
“Prior to the President’s return to West Palm Beach, USSS discovered what appeared to be an elevated hunting stand within sight line of the Air Force One landing zone,” the FBI director told Fox News Digital, later confirming on social media that “the FBI is investigating” what Patel called a “suspicious stand” near the zone.
