The Hill has reached out to the White House for comment.

It is illegal to use the presidency for personal profit because of the Emoluments Clause of the U.S. Constitution.

Later this month, a federal judge will hear an appeal from the president in attempt to block a separate case in which the president is accused of violating the Emoluments Clause by accepting payments through his hotel in Washington.
