The Trumps were worth billions well before he became President. There is zero reason for him to do anything illegal for ANYBODY. He prefers to do his deals straight in the face so he can celebrate his wins as loudly as possible.
The primitives do not know what being a multi-billionaire. That is a whole strata well above the lowly politicos who became mere millionaires on the taxpayers' dime like the clintons, obozos and xidens.
People at the multi-billion dollar level of assets do not care about money except as a way of keeping score and to extend their legacy.
