Trump's sister, the federal judge, just resigned to halt the investigation into her participation in the giant tax fraud scheme to transfer father Fred's money to his kids. I think all the ins and outs, shell corporations, etc. of that scheme are well known. They avoided millions of dollars worth of inheritance tax. There is no statute of limitations on intentional tax fraud.

The apples don't fall far from the tree. I think the only innocent Trump is Barron.
