I am not assuming anything.
Hunter had the most intense of investigation the DoJ can do to look for those 'other crimes' in the form of a Special Counsel and he found nothing.
This is what magats do. They just keep claiming that 'the next investigation will find what the prior one did not', and thus believing the person still guilty is fine.
Are you proposing that Hunter should get another Special Counsel? And if that one fails another after that? Because that is what COmer bragged about with Benghazi, and how just the non stop investigations harmed Hilary.
