Taxpayers would likely foot the bill to retrofit President Trump's new jet, which could be more than twice the plane's $400 million value.

The nation of Qatar offered the Trump administration a Boeing 747-8 for use as Air Force One. Trump called the plane a "gift," in a post on his social media site, Truth Social. A representative of the administration clarified that Qatar "has offered to donate a plane to the Department of Defense," not to Trump himself.
