The entire Trump legacy, in business and law/politics, is stained beyond repair.
The only hope any single of his family has, to avoid being associated with the vile narcissism and insanity that he brought to US culture and politics, is to disassociate from the Trumps completely. I am not saying that it would be easy to do so but I am indeed suggesting that there is no way whatsoever for them to escape the stain on 'Trump'.
He has thoroughly ruined everything he built legacy-wise. Good job Donald, your grandchildren will grow up despised for sins of their grandfather.
