The Emoluments Clause of the Constitution prohibits U.S. officials from receiving payments from foreign governments. Lawyers started warning about the potential for violations at Trump’s Washington hotel and overseas properties after he won the election, but the clause didn’t start applying to Trump until he took office on Jan. 20.

The Jan. 23-26 hotel stay paid by the Saudis likely a violation of the foreign emoluments clause.

“The problem with Donald Trump’s constitutionally forbidden foreign government cash and other benefits is not just that any one particular payment is problematic — it’s also a systemic problem,” said Norm Eisen, who was President Barack Obama’s ethics czar and is now part of a lawsuit accusing Trump of violation the Emoluments Clause. 



“It’s another tile in the mosaic of unconstitutional behavior.”
