John Dowd is not serving his client well.

Dowd, a lawyer, represents Donald John Trump. Dowd now is calling for an end to an investigation led by another lawyer, special counsel Robert Mueller, who’s looking deeply into issues involving Trump, his campaign, his transition to the presidency and the presidency itself.

Now that Attorney General Jeff Sessions has fired deputy FBI Director Andrew McCabe, a key player in Mueller’s probe, Dowd says it’s time for Mueller to wrap up this investigation.

If I were to put myself in Mueller’s shoes I might be asking: What in the world is Dowd trying to hide? Why does he want me to end an investigation that is growing more complicated by the day, if not the hour?

Thus, in my view Dowd has done his client a disservice. Oh, but then there is this: Donald Trump wants the investigation to end as well. He’s called it a “witch hunt,” which it isn’t. Deputy Attorney General Rod Rosenstein, who selected Mueller after Sessions recused himself, said Mueller has done nothing wrong and that his probe should continue.

At issue, of course, is the “Russia thing,” and whether the Trump campaign “colluded” with Russians seeking to meddle in our 2016 presidential election.

The U.S. House Intelligence Committee’s Republican leadership has said there is “no collusion,” which prompted Trump to declare that “Congress” has found nothing wrong. Oops! He didn’t say that the GOP leaders on the committee have drawn that conclusion.

Oh, but the Mueller probe has many more trails to explore, many more leads to follow.

He’s a long way from finishing his work.

John Dowd needs to pipe down and let the special counsel do his job, get to the finish line and if he finds nothing there — as Trump keeps insisting — he needs to tell us all himself.
