Emoluments

Jimmy Carter sold his peanut farm so there'd be no suggestion of self-dealing.
Article 1, section 9:

“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.”

Article 2, Section 1:

"The President shall, at stated Times, receive for his Services, a Compensation, which shall neither be increased nor diminished during the Period for which he shall have been elected, and he shall not receive within that Period any other Emolument from the United States, or any of them."

Here's a list of people have been reported at some Trump property or another, which means they've put money in Trump's pockets. And since these assholes don't operate on their own dimes, it means they've put my tax dollars in Trump's pockets:
