Trump’s plan to accept a $400 million plane from Qatar has ignited a full-blown firestorm among Democrats in Congress

Qatari officials said the plane was being given by the Qatari Ministry of Defense to the Pentagon but Trump said the Boeing 747-8 jet will be used as Air Force One—the official presidential plane and according to multiple reports, after he leaves office, it will be transferred to the Trump presidential library foundation.

Article I includes a ban on anyone serving in government accepting “any present, Emolument, Office, or Title, of any kind whatever, from any King, Prince, or foreign State” unless Congress approves. Article II says, in part, that the president cannot receive any emolument from a U.S. state.
