Congressional Republicans keep saying special counsel Robert Mueller’s probe into the Russia collusion matter has gone on too long. It has run its course, they say. It’s time to wrap it up.

Allow me this respectful dissent. No, it hasn’t gone on too long. It’s not yet time to call it good. Mueller is getting closer to the end. To that we all can agree.

Mueller’s investigation has scored some key victories already. He has obtained guilty pleas from principals involved in Donald Trump’s 2016 presidential campaign. It’s not a “witch hunt,” which Trump has alleged far too often and with far too much emotion.

I, too, want this probe to end. I simply want it to end on Mueller’s terms. The Justice Department appointed him special counsel amid near-universal praise. Democrats and Republicans alike cheered his selection by Deputy Attorney General Rod Rosenstein.

What has changed since that appointment? The way I see, the change occurred when Mueller rolled up guilty pleas and, in the case of former Trump campaign chairman Paul Manafort, conviction on eight felony counts; plus, Manafort has pleaded guilty to two more allegations and has agreed to cooperate with Mueller’s team.

So now the GOP wants the investigation to end?

C’mon, ladies and gentlemen. You cheered this man’s selection. Let him finish his job.
