this case has branched out into different areas, areas where Trump has no pardon power. I'm guessing that Mueller knew that Barr would cover for Trump, so the Dems and Republicans will be fighting over getting this information out to the public for the foreseeable future. the other thing that a lot of people aren't seeing is that Mueller has partially told the story through his indictments. People who are saying there is absolutely no connection obviously haven't been reading the indictments. Proving "collusion" beyond a reasonable doubt is not easy, that doesn't mean that Trump has been "exonerated." We will never see the entire report, but hopefully we get to see enough that tells us what happened.
