Donald John Trump was never a successful businessman as he claims. He obtained his money from his family and from repeated bankruptcies. He rarely paid taxes to the USA Treasury.
He has used propaganda all his life to float ideas of grandeur to the public. The propaganda was successfully in promoting merchandise and a failed university.
There is no reason to believe a single word Donald John Trumps says.
Donald John Trump is a pathological liar. He is always grieving for his public image. People hate him, use him for political whipping post, others lie about him all the time and he just never seems to find justice in his life. Justice is hard to come by when chronically lying.
