Maybe Barr's testimony today will shake something more loose from Mueller.

2. Is this supposed to be sarcasm? Mueller was Dubya's FBI Director

He's a longtime Republican legal establishment power player from the same clubhouse as Barr (they're good friends, incidentally). He had the chance to "lay down the law" in his report and instead he punted on everything.

Mueller will volunteer no help to us. He probably won't disgrace himself the way Barr has, but he will equivocate and demur and punt and pointedly refuse to level any direct shots at either Barr or Trump. At best, his position will be "the report speaks for itself, reach your own conclusions."
