Mueller will testify before Congress.
At nearly 400 pages, that's a lot of material if it really "totally exonerates" Trump. And if the report really does "totally exonerate" Cheese Hitler, then why are they trying to so hard to bury it? Or try to keep it from coming out before the 2020 election?
It's obvious, of course. Trump doesn't want it out because he knows what's really in it.
(By the way, Trump keeps telling that lie about the New York Times. No, they were not forced to apologize, nor did they. So why does Trump have to lie so much, hmm? What's up with that? He even lies about where his father was born.)
