If all this spying on Trump didn't start well before what we have been told, I will eat crow.
Mueller is providing the coverup by providing HIS timeline. What he doesn't know is the REAL FBI timeline which has since been destroyed, missing, burnt, hidden etc etc.
He’s not about to dump anything, the investigation will go on for another 2 years.
I think they know he will issue his report before Barr is confirmed because he knows that Barr will demand a re-write that will require him to only include facts substantiated by solid evidence and is devoid of any inferences of wrong doing that is only speculation. The Dems are scared of Barr, not so much of the current acting AG.
All of the articles lately concerning the report are down playing its bombshell expectations. They know it will not reveal any crimes/collusion and need to tamp down expectations.
