At this stage if they were to charge Trump (and Turmp did not pardon himself) any good defense attorney will be able to raise a very strong reasonable doubt argument.
Mueller may have botched one more high profile case by bringing on such a biased team.
Can you imagine the discovery battles.
A defense attorney is going to ask for everything.
And bring up the fact that Mueller's team has a propensity to bury exonerating evidence and is highly biased against Trump.
I can't even imagine what the team will do about the dossier and what it was used for?
I also not, Trump Junior may even have a credible case for entrapment since the govt may have been paying for fusion gps. so he should be able to get all the info related to fusion gps and comey and hillary and ohr and ohrs wife and McCabe maybe.
Mueller should have had the brains to get people not connnected to these issues if he really wanted to win.
Right now... its over for him.
