Nor would I. But, I Mueller ain't thinking straight. His hatred for all things Trump has unglued him.
Surely Mueller is surrounded by Trump haters.
But if he were unglued with hatred for Trump all he had to do was find obstruction in his report and Trump would be over. Wouldn't matter if there was an iota of truth, he could have done it and walked away from any responsibility for what ensued. He didn't and the rats, who clearly expected something else, were shocked.
There can be only a few reasons why he didn't:
One, he's worried about info that soon will become unclassified refuting his 'findings'; or
He values his friendship with AG Barr.
Regardless we just KNOW many if not all major figures on his team would've crucified Trump in a heartbeat but for some reason Mueller, and I believe it was Mueller, stopped them. I do not believe he will turn around and allow the rats to get what they were refused in his report in any upcoming hearings.
