Barr is a Bushie fixer and part of the swamp. POTUS is going to have to dig deep and away from Washington to find an AG with some teeth and who's ass is not owned. However, I have heard that Barr is very frustrated. The swamp deep state is very ensconced within Justice and he cannot seem to get any movement. So, I am not sure what impact replacing the AG will have.  It sounds more like they need to house clean the FBI and Justice. Since these government employees cannot be easily fired, they may have to be moved. Transfer them to offices somewhere else in the country but force them to leave Washington. Then bring in some new staff. I don't know how else they are going to be able to move some of this along because the problem is not necessarily coming from the top. The SES deep state is one of our biggest obstacles to getting justice and will not be easily remedied.  POTUS is learning that public does not work like the private sector. He is used to giving an order and having it done. Not so within the public bureaucracy. Those wheels turn painfully slow. I have worked in both areas and trying to get anything done in the public work area is maddening. It is a place where much busy work gives an appearance of productivity but in reality ver  ffa  y little is actually accomplished - especially at the middle management levels. There is lots of busy work in order to justify paychecks, but the end product leaves much to be desired and is most only of use to the bureaucratic bean counters.
