(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.
