Deputy Attorney General Rod Rosenstein assures us that Special Counsel Mueller is doing a first-rate job probing the possible (but thus far undiscovered) complicity of Trump associates in Russia’s election meddling. That being the case, I’m wondering: Would the Trump Justice Department be up for applying Mueller’s approach to the Clinton caper?

No, I’m not suggesting that DOJ direct the FBI to break into Mr. Combetta’s home with guns drawn in the dead of night, as Mueller did with former Trump campaign chairman Paul Manafort. I’d save the brass-knuckles tactics for hardened criminals, as the law intends. I’m talking about the aggressive but wholly legitimate step Mueller has taken: Calling BS on attempts by criminal suspects to use lawyers to conceal their schemes.

Back in November, we catalogued the stark contrasts between Mueller’s brand of hardball and the kid-gloves treatment given to subjects of the Clinton-emails investigation. The most significant of these involved the attorney–client privilege. Mueller persuaded a federal judge to force an attorney for Manafort and his co-defendant (Richard Gates) to testify against them in the grand jury.
