As to Trump, I think he's being false investigated, but I find it to be somewhat hilarious and somewhat of a poetic justice because he constantly cheer-leads cops. Good portion of cops are dim-wits that are as useful as tits on a boar. That goes for many in the FBI and I have personal experience to reflect on.
I say sit back and enjoy the shitshow without getting all emotional about the outcomes. I'm fairly certain it will end up much ado about nothing and will be just a PR campaign. Trump will issue pardons which will hurt him with few moderates, but all and all it will be a wash. Waste of air time and coverage of more pressing news.
And YES, Mueller was a CAN FBI director. For few of you who ever heard him speak and answer questions, he's no more truthful or eloquent than Loretta Lynch. From 2013 about IRS targeting tea party groups and how FBI conducted investigation. Mueller claimed he didn't know who the lead investigator was. Holy mother of god.
