U.S. President Donald Trump's plan to accept a $400 million airplane from Qatar raises a raft of questions about the scope of laws that relate to gifts from foreign governments and are intended to thwart corruption and improper influence,

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.
