Mueller (R), appointed by a Republican Justice department (Deputy Atty Gen. Rosenstein (R)) to investigate a Republican administration, and you think the problem is that there aren't enough republicans involved?Mueller and his group of hand picked Hillary minions have done exactly as I expected...providing cover for her by leaking news of secret Grand Jury indictments out at the very moment that she and the DNC have been exposed in the fake dossier scandal!
This "opening salvo" as you've described it...is nothing more than an attempt to manage the news...something that the Clinton camp has been doing all along.
I think the "problem" is leaks from a Grand Jury. It's against the law. Someone from the group that Mueller has assembled has done exactly that and should be held criminally liable. What political party one belongs to has nothing to do with it.
