Mueller to Barr: "There is now public confusion about critical aspects of the results of our investigation. This threatens to undermine a central purpose for which the Dept. appointed the Special Counsel: to assure full public confidence in the outcome of the investigations." https://t.co/BdUEcEs98s

This is horse puckey, just like the claim that they were surprised Mueller was not coming to an obstruction conclusion. pic.twitter.com/5tWVYtvf1P

Barr believes in a unitary president which is why he feels that Nixon got a raw deal from the Congress when they impeached him.
As Nixon stated “When the president does it, it’s not illegal.”
That is what Barr firmly believes.
Unfortunately for Barr he picked Trump to be his test case and will suffer the consequences of that decision.
When the House gets Mueller before them they had better have designated counsel question about redactions because there is more controversy to be had.
