James Herbert, an assistant U.S. attorney for the District of Massachusetts, said he was compelled to issue the stunning rebuke Thursday over concerns Barr was politicizing the Justice Department.

“While I am a federal prosecutor, I am writing to express my own views, clearly not those of the department, on a matter that should concern all citizens: the unprecedented politicization of the office of the attorney general,” Herbert wrote in The Boston Globe. “The attorney general acts as though his job is to serve only the political interests of Donald J. Trump. This is a dangerous abuse of power.”…

“William Barr has done the president’s bidding at every turn. For 30 years I have been proud to say I work for the Department of Justice, but the current attorney general has brought shame on the department he purports to lead,” Herbert wrote.
