Look, Comey dishonored himself, ruined his good name forever and needs to resign. But, that said, the countercase is that now that this is no longer a criminal investigation it is all fair game for the public and for Judicial Watch discovery in its ongoing FOIA case.

But it is also Comey's undoing, he has failed to uphold justice [reduntantly "equal justice for all"], and he must go. Just go!
