This is the emoluments clause:

    No Title of Nobility shall be granted by the United States: And no Person
    holding any Office of Profit or Trust under them, shall, without the Consent
    of the Congress, accept of any present, Emolument, Office, or Title, of any
    kind whatever, from any King, Prince, or foreign State.[5]

And the reason they put that there is the obvious one: this is as corrupt as corrupt gets.
