Conversation so far:
Did Frank Hague commit any questionable acts?

Did he do anything illegal?
He was also able to avoid prosecution despite numerous federal and state investigations in part due to the fact he took most of his kickbacks in cash.

Question: Did anyone attempt to prosecute him?
Self-contained rewrite: Did anyone attempt to prosecute Frank Hague?
