Today Donald Trump tried to give credit where credit is due. While speaking in Charleston, South Carolina, he mocked the “shrill” Hillary Clinton for denying that she started the birther movement, doubting that President Barack Obama was born in the United States before he did.

“[I]n 2008 she was the original birther,” he said. “She’s the one that started the whole thing. Hillary is a birther.”

Coincidentally, Clinton had just blamed Trump for getting people to think exactly that, now seven years after she said that Obama is a Christian, not Muslim, “as far as I know.”

“Did you or your campaign start the whole birther thing?” CNN anchor Don Lemon asked Clinton on Tom Joyner Morning Show. “Did you have a confrontation with the President?”

“That is so ludicrous, Don,” Clinton said. “You know, honestly, I just believe that—first of all, it’s totally untrue. And secondly, the President and I have never had any kind of confrontation like that. You know, this is such a bad example of what’s wrong with instantaneous reactions, and the Americans getting all worked up, and people feeding into prejudices and paranoia like Donald Trump.”
