The Constitution" has something called The Emoluments Clause. That's just a fancy, 18th century word for no foreign government payments. And Donald Trump is collecting foreign government payments and other benefits throughout his business.It is a direct violation of "The Constitution" and unless he divests, not just operations, he must divest from all business interests or he will be in violation of "The Constitution" from day one.
People are studying whether there's a cause of action that competitors, for example, would have if they're harmed by these foreign government payments.
