We've probably all seen the emoluments clause raised as one way he may be breaking the law. I'm not a legal expert but I would assume, if it's true, that breaking the Constitution would be illegal?
"The Title of Nobility Clause is a provision in Article I, Section 9, Clause 8 of the United States Constitution, that ... restricts members of the government from receiving gifts, emoluments, offices or titles from foreign states without the consent of the United States Congress."
I suspect we will hear a lot more about the "consent of Congress" in the next 6 months if this has any merit.
