Good question. I've thought about that possibility because we know that any in indictments handed down my Mueller would necessarily wind up at trial with DC Jury Pools… definitely not optimal. Much better that those indictments be passed along to Huber (UT) or others.
But how about this possibility. What if Barr tells the Fake News that it is in the public interest that the Mueller Report NOT be made public and NOT even passed on to Congress. Wouldn't that peak the interests of the D's and the J.Q. Public?
