There they go again.

The Obama White House, first in the person of press secretary Josh Earnest and now in the person of the president himself, is perpetrating a falsehood of some significance on the American people. It has to do with the denial by Messrs. Earnest and Obama that when the president used the dismissive phrase “jayvee team” in his interview with David Remnick of the New Yorker, he didn’t have ISIS in mind.

Here’s the exchange that took place in his interview on Meet the Press:

CHUCK TODD: Long way, long way from when you described them [ISIS] as a JV team.

PRESIDENT OBAMA: Well, I–

CHUCK TODD: Was that bad intelligence or your misjudgment?

PRESIDENT OBAMA: Keep– keep– keep in mind I wasn’t specifically referring to [ISIS]. I’ve said that, regionally, there were a whole series of organizations that were focused primarily locally. Weren’t focused on homeland, because I think a lot of us, when we think about terrorism, the model is Osama bin Laden and 9/11.

But as I laid out in a fair amount of detail two weeks ago, there’s simply no question that the president was referring to ISIS. Glenn Kessler of the Washington Post weighed in a week later, making essentially the same case, and awarding the White House four Pinocchios for their dishonesty on this matter.

This is no small matter. Mr. Obama’s misjudgment on ISIS was extraordinarily costly. It was a complete misreading of the situation, long after others were warning about the nature of the ISIS threat. This mistake ranks among the worst errors of the Obama presidency, which is saying quite a lot. President Obama knows this, which is why he’s frantically trying to pretend he didn’t say what he so clearly said.

The problem is in this whole process the president of the United States is distorting the truth. He’s doing so willfully. But this deception will not only fail; it will further undermine his credibility, which is already at a low ebb. As Mr. Obama said in 2008, “I mean, words mean something. You can’t just make stuff up.”

Mr. Obama is at war with reality, and reality is winning.
