Wow, certain posters here need to stfu and go and learn who Mueller is before continuing to demand what he should have done by projecting what they think they would have done.
The actions they keep wanting him to have taken are the very antithesis of the man in question, a man that speaks on the facts, presenting them for others to draw conclusions, rather than giving those conclusions to them. A man who was well liked and known by both parties previous to the whole Trump thing as being extremely impartial to a fault. A man who plays it to the letter of the book.
He showed exactly that in his forced testimony, a testimony that he had stated previously that he was unwilling to do, and that would be no more than the Report.
He was never going to give the Democrats, nor the Republicans the sound bytes they wanted. Just go and watch what the media was saying about him prior to the testimony. They knew exactly what to expect from him.
And in the end what he said wouldn't really matter anyways. Those that don't want to hear what was in the report would still be ignoring it like they are now.
Heck, he did go off script when talking Russian interference, declaring not only that they did it, but that they were still doing it and that other countries were developing the techniques too. He couldn't have given a clearer warning, and what did Moscow Mitch do that same day?
It's time to stop shooting the messenger, he did his job to the letter, he has given the facts, and the facts are damning. Those you should be after are the ones who have the facts and refuse to look at them or act on them.
