The USA Constitution is the law. Just that simple. For two years the US Congress did nothing in upholding the USA Constitution and due to that, now the Trumps and Kushners believe they can conduct themselves as they please without worry.
“[N]o Person (click here) holding any Office of Profit or Trust under [the United States], 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.”
Foreign Emoluments Clause, U.S. Const. art. I, § 9, cl. 8.
THEY VIOLATED THE USA CONSTITUTION AND NO ONE DID A THING until members filed suit to end the abuse. (click here) I think the violations go well beyond Trump and also extend to his advisers. I don't care if they state they are volunteers, that is just another lie. They are using their power within the White House for their personal enrichment.
