1/ Short thread: William P. #Barr has a history of working closely with Robert #Mueller in @TheJusticeDept. I think that their #DOJ association is a good basis to presume that Barr thinks highly of Mueller as a law enforcement professional & as a person.
2/ In the #Bush41 administration, beginning in 1989, Barr & Mueller worked under AG Dick #Thornburgh. Mueller was Thornburgh’s principal aide on criminal matters. Barr was Assistant AG heading the Office of Legal Counsel (OLC).
3/ In 1990, the Deputy Attorney General (Donald B. Ayer) resigned. President Bush appointed Barr to succeed Ayer as DAG.
4/ In that same time period, Asst. AG Edward S.G. Dennis, head of the Criminal Division, also resigned.
5/ President Bush appointed Mueller to succeed Dennis as AAG heading the Criminal Division.
6/ When AG Thornburgh resigned in 1991 to run for the U.S. Senate, Barr became Acting AG. President Bush soon appointed Barr to succeed Thornburgh as AG.
7/ AG Barr & AAG Mueller served together in DOJ until the Bush administration concluded in January 1993.
