In a matter of days after his being elected as President of the United States, Donald Trump decided to put his business empire in the hands of his adult children. Roughly a month later, in recognition of the intractable conflicts-of-interest problem even were his three eldest children to run his roughly 500 companies, he announced that he would sever his ties with his empire; after all, he would have his hands full as the federal president of another sort of empire: The United States of America. Even so, he did not mean to divest, suggesting that conflicts of interest involving his brand could be salient through his tenure as U.S. President. It is important to remember that nothing in federal law prohibits the President from continuing to run his own business; the conflict-of-interest rules that apply to other federal officials do not apply to the office of the president. Even so, enormous external pressure was being brought to bear on the president-elect to divest completely from his businesses.
