It isn't known exactly why at this point, but Donald Trump's personal jet has landed at Cheyenne Regional Airport.

The Boeing 757, sometimes known as "Trump Force One" last landed at the Cheyenne Airport in May of 2018, taking first daughter Ivanka and her family to a vacation trip in Saratoga.

The latest landing of the Trump jet in Cheyenne is believed to have happened around mid-day Thursday.

The plane is Trump's personal airplane, not one of the official presidential planes known as "Air Force One." President Trump was reportedly on board Air Force One at the same time the Trump plane was in Cheyenne, so the Trump plane was presumably not carrying the president.
