Donald J. Trump does not get it.

He keeps yapping about the “rigged witch hunt,” which is how he describes the investigation by special counsel Robert Mueller into Russian meddling in our 2016 election.

He said over the weekend that the Mueller probe is harmful to the country.

Oh … my.

No, Mr. President. The harm to the country has come from the Russians who hacked into the Democrats’ election system. The harm was done by goons who sought to influence the election outcome. The harm occurred — and is occurring at this moment — by the discord that continues to tear at the fabric of our electoral process.

The president is going to meet very soon with Russian strongman Vladimir Putin. He promises to bring up the meddling matter with him. Putin’s response likely won’t be reported fully; Putin and Trump will meet privately, just the two of ’em in the room. Nor will we likely know to what extent Trump calls Putin out on the meddling.

With all this as prologue, we keep hearing from the president about the evils of a “rigged witch hunt” that so far has produced multiple indictments, several guilty pleas, witnesses cooperating with the special counsel.

That is not a “rigged witch hunt,” let alone a probe that harms the United States of America. It will strengthen the nation once it’s completed — irrespective of what Robert Mueller concludes.

The harm is being done by those who have corrupted our election system. If only the president could acknowledge the obvious.
