Oh, how I wanted William Barr to be the right remedy for a Justice Department under siege from the president of the United States.

The attorney general took office after a contentious confirmation hearing. It is the AG’s second tour of duty at DOJ. He’s an experienced hand and reportedly a fine lawyer with a steel-trap legal mind.

He has been a disappointment to me. Yes, I am a fervent critic of the guy who nominated William Barr to lead the Justice Department. Donald Trump had savaged Barr’s predecessor as attorney general. Why? Because Jeff Sessions did the right thing by recusing himself from the Russia probe.

Barr stepped in and has — according to his critics — acted more like Trump’s lawyer than the nation’s top law enforcement official.

Now we hear from former FBI director James Comey, another damn good lawyer, who has weighed in with scorching criticism of Barr.

Comey said Barr is “echoing conspiracy theories” about the origins of former special counsel Robert Mueller’s exhaustive investigation into alleged collusion with the Russians. Barr, according to Comey, needs to present facts along with his assertions. “This is what Justice is about,” Comey said via Twitter.

Barr also has been critical of Mueller for declining to conclude whether Donald Trump obstructed justice. But … why? Mueller reiterated this week what he wrote in his lengthy report that he couldn’t indict Trump because of Justice Department policy that prohibits charging a president with a crime. So, he said his team couldn’t exonerate Trump, which to my way of thinking is the same thing as saying that the president committed a crime. That sounds as though Mueller drew a conclusion.

I truly wanted William Barr to step up, to steady the DOJ ship and guide the Justice Department into carrying its role as an impartial administrator of justice.

That doesn’t appear to be happening. Thus, the chaos continues in a federal agency that demands calm, firm and steady leadership.
