According to media reports such as the Fox News Network and the Beast Daily, the day before the arrival of U.S. President Trump at Palm Beach International Airport in Florida, the U.S. Secret Service discovered a suspected "hunting shelf" facility within the view of a landing area of the presidential aircraft "Air Force One" on the 17th. White House officials said that because of Palm Beach International Airport "strengthened security measures", Trump on the 19th changed to a short ladder fast boarding.

The alleged "hunting rack" facility was found on a tree from which it was clearly visible to Palm Beach International Airport. Fox News Network called the facility a possible "sniper position" in the report. FBI Director Patel said the agency was leading the investigation, and no people have yet been found involved.

The short ladder of the Air Force One is shorter and more robust, allowing boarders to enter the aircraft from the womb, rather than the higher ladder used by the president when entering the aircraft.
