President-elect Donald Trump says he wants to cancel a contract with Boeing to build the new Air Force One. He made the announcement on Twitter Tuesday morning.
Trump said costs are out of control, more than $4 billion for the plane.
Business Insider reports Boeing's stock fell in early trading Tuesday after Trump's tweet.
Critics say Trump's numbers are way off. Politico reports Boeing is under contract to build two planes in Washington and Senator Patty Murray said Trump should find out how defense contracts work before he tweets.
