The reason Barr said Mueller does not need to testify is that both have been told they are in violation of rule 57.7, which prohibits the dissemination of information that could prejudice the administration of justice. The lawyers for Concord Management filed an order to hold them in criminal contempt. The judge denied the motion but told Barr and Mueller to cool it.Barr said that Mueller does not need to testify on the 17th, as it would be a public "spectacle". Good for Barr, let the Barr, Huber, Durham, and Horowitz reports do the talking, and indicting, to the deep state.
Robert Mueller's entire case is falling apart and the entire sordid affair is going to be covered up. These people protect their own.
Inside the NSA, FBI, CIA and other intel agencies there are patriots, not saying partisans, that know misuse when they see it. I'm amazed that Binny and Johnson were not on the MSM telling their counter-narrative to the Mueller Report. I'm sure Barr, Huber, Durham, and Horowitz will find enough data and whistle-blowers to set the record straight. You may be right that a coverup happens, I'm betting that Trump, Barr, Pompeo and the Senate (Rubio, Graham et.al.) have enough clout to out the deep state coup/conspiracy.
The "real protectors" will protect whomever needs protecting....
