The FBI is searching for clues at a stand of trees just off the tarmac at an airport in the City of Palm Beach, Florida, where President Donald Trump flies in and out.
A US Secret Service agent noticed during a security survey around the airport what appears to be a hunting stand, a platform that's been added among the branches of a tree -- the problem is the pallet-like scrap of wood provides a direct line-of-sight view of the airport tarmac where the President would normally get on and off Air Force One.
FBI agents have been seen examining the tree and nearby pathways in an attempt to find out if anyone's used the tree's perch above the tarmac.
Secret Service Chief of Communications Anthony Guglielmi told Fox News on Sunday that his agents are "working closely" with the FBI in addition to local law enforcement in Palm Beach County.
No one has been seen in any nearby areas or near the tree, he said, so there are no suspects.
President Trump flies regularly in and out of Palm Beach International Airport.
