Founding Fathers and preventing a corrupted Presidency

WaPo covered why the Founding Fathers wanted the President to have a salary and it highlights that they did NOT want the President to have business ties. Since Trump has promised to donate his salary (which he has not done yet) and has not divested himself of business (really, really - his sons running the company??) we should be very concerned. So much for loving the country and the Founding Fathers. Trump is not wrapping himself in an American flag - he is wrapping himself in a for sale sign.
