(New York, NY)  --  President-elect Donald Trump is slated to meet again today with Boeing CEO Dennis Muilenburg to discuss the company's contract to build the next-generation version of Air Force One.  Trump tweeted in early December that Boeing was "building a brand new 747 Air Force One for future presidents, but costs are out of control, more than four-billion dollars.  Cancel order!"  Since then, Muilenburg said that Boeing could build a new version of Air Force One for less than four-billion.  This will be the second meeting between Trump and Muilenberg since the election.
