The U.S. Secret Service declined to comment and the Air Force referred questions to the White House. The NATO summit in Ankara, Turkey last month, ended with a ruse to safely get President Trump out of the country due to Iranian assassination threats against him, according to The Washington Post. In Ankara, Trump boarded the old Air Force One jumbo jet in view of television cameras ahead of the plane flying to the United Kingdom. The Air Force, which maintains the fleet of executive travel aircraft, has referred all questions to the White House.
