I don't care who the Attorney General is. It really doesn't matter when the only criteria involves serving as Trump's "Roy Cohn". However, it is clear that Barr's interview with ABC News was purely for public consumption. It was all about spectacle. The resignations of the 4 prosecutors has created a perception that Barr wants to fight, and this interview was a part of a public relations strategy for Barr to portray himself as being independent of Trump's influence, when that doesn't appear to be the case.
