Donald J. Trump has a “no collusion” fetish.

He keeps invoking the “no collusion” mantra even when it’s irrelevant to the issue of the day.

Take the Paul Manafort sentence handed down the other day. The president’s former campaign chairman got a 47-month sentence for tax fraud and assorted other crimes. None of them had a thing to do with the allegations that the campaign “colluded” with Russians who attacked our electoral system in 2016.

Yet there was the president of the United States, crowing about how the judge found no evidence of collusion with Russians.

Hey, Mr. President? That issue isn’t even on the table in this discussion. Manafort’s sentence didn’t have a single thing to do with collusion.

Oh, and Mr. President, we’re still awaiting Robert Mueller report that he supposedly is preparing to submit to Attorney General William Barr.

That is where we’re going to find out — more than likely — whether there is any Russian hanky-panky related to your 2016 presidential campaign.

So . . . POTUS needs to settle down and wait for the report silently.

Yeah, I know. I’m asking for the impossible.
