Trump lives off of his "investors" money. Investing with Trump is a losing proposition, because Trump is more of a con man than a business man.
And we can see why he refuses to reveal his tax returns.
Funny how Republicans defend his right to privacy, yet if Hilary had refused to turn over her taxes, they would bay for her blood. (I don't mean figuratively, they would want blood samples to see if she were an alien or who knows what.)
