“Bill was just an attack dog that was loosed on us”

The WSJ today has a story about what Bill Barr, Trump's nominee for Attorney General, has been doing since leaving DoJ in 1994: Trump’s Attorney General Pick Earned a Reputation as a Fighter in the Corporate World (originally published as 'Aggressive Tactics Mark Attorney General Nominee Attorney General Nominee Known for Assertiveness.'). The short answer is that Barr has been very busy. He became a central figure in the Wild West world of telecommunications deregulation between 1996 and 2008, renowned for his pugnacity. I'm not taking sides on the merits of the Telecommunications Act of 1996 and its aftermath, but anyone who thinks Barr is simply a lapdog for the Washington Establishment who will not be a match for Mueller or Rosenstein will probably want to reconsider. What he clearly is, is a very aggressive advocate for his clients. As AG he will be an advocate, most broadly, for the Constitution and laws of the United States, but in that capacity he has a well established record as an aggressive defender of the Executive Branch.
