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

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.

Trump previously attacked foreign and even Qatari donations to the Clinton Foundation. Now he wants to accept the biggest gift of all.
