Since there will be hundreds of people talking about Trump violating the Constitution I thought it might be a good idea to read the actual line in question.

The Emolument Clause of the Constitution.

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 I, SECTION 9, CLAUSE 8

I can see where the Trump people will see some wiggle room here…though his youngest is already named Barron so that doesn’t count.
