The Hastert conviction has nothing to do with any past sexual abuse. It is based on the financial manipulations involved in the payments to individuals who may have been sexually abused. Yes, he may be sued by some of the individuals he abused and to whom he was making payments. I assume that the lawsuits will be based on breach of contract, not sexual abuse.
Good point. Regardless, his new friends on the cell block will greet him like any new arrival. Punishment enough?
He will also serve 15 months in prison somewhere.
