Legal teams for the U.S. and Qatari governments are still working out the details of an agreement for Doha to transfer a luxury Boeing 747-8 jet that President Trump hopes to use as Air Force One, more than a week after the Pentagon said it had taken physical possession of the aircraft.

The Pentagon officially took control of a Boeing 747-8 jet “gifted” by Qatar to President Donald Trump, though legal questions remain unresolved, according to Benzinga. According to The Hill, Doha is requesting a formal memorandum clarifying that the arrangement was initiated by the Trump administration and absolving Qatar of future ownership obligations.
