YOU should ask yourself the following. Why should ANY president, or any member of his extended family, profit at all from business entities that Trump has not severed himself from?
And, of course, why should Trump, alone among all presidents over the past 50 years, not reveal his income tax returns?
Wouldn't the release of his tax returns answer the question you pose?
ask yourself this. Is Trump profiting more as a politician, than he did as a business man?
