When elected, most presidents either sell their assets or put them in a blind trust. Isolating a president’s financial interests from their time in office has been a norm for decades: from Jimmy Carter giving up his peanut farm to Barack Obama liquidating his assets. But Donald Trump is not like most presidents. He’s said he won’t divest from his businesses, even though his real estate deals around the world open up countless opportunities for conflicts of interest. His unprecedented decision may violate the “emoluments clause” of the Constitution — a rule that’s existed longer than the American republic, but has never before faced scrutiny in the courts. On Tuesday, a panel of Fourth Circuit judges heard an emoluments case and their decision appears likely to send the fight to Supreme Court.
