Do you believe that Mueller found evidence that "members of the Trump Campaign conspired or coordinated with the Russian government" and choose to cover it up? Why would he do that? Do you really believe that Mueller's hand picked "I'm with Her" lawyers wouldn't leak that if he attempted to do so for whatever reason?
What do you think that 'establish' is doing in the middle of the sentence?
It's a measure of the level of proof, but its meaning is unclear. Does it mean 'establish beyond a reasonable doubt' ie criminal level of proof? Does it mean 'establish on preponderance of the evidence' ie civil case level of proof?
What it does not mean is NO evidence of conspiracy or collusion, which is what you claimed.
We don't know what Mueller has said in the report, we only have carefully selected quotes from Barr. The Mueller team has not leaked anything to date and I'm not expecting them to.
