Donald Trump on Wednesday accused Hillary Clinton of starting the so-called “birther” movement, which raised unfounded questions about President Obama’s birthplace and American citizenship.

“You know who started the birth movement? You know who started it? Do you know who questioned his birth certificate, one of the first? Hillary Clinton,” Trump told CNN’s Wolf Blitzer Wednesday. “She’s the one that started it. She brought it up years before it was brought up by me.”

The real estate mogul was responding to video footage of Clinton blasting Trump for questioning where the president was born and demanding that he release his birth certificate.

“The leading Republican contender is the man who led the insidious birther movement to discredit the president’s citizenship,” Clinton said during a campaign event Sunday.

Trump dismissed those claims, repeating an oft-cited – but debunked – suggestion that Clinton herself was the first to question Obama’s birthplace. Several independent fact-checkers investigated the claims and concluded that they were unfounded. wrote last year that, “[w]hile it’s true that some of her ardent supporters pushed the theory, there is no evidence that Clinton or her campaign had anything to do with it.”

Pressed on where he stood with regards to the president’s birthplace today, Trump said that he’s not interested in discussing the issue further.

“I don’t talk about it anymore because every time I talk about it, it becomes a story, so I don’t want to waste my time talking about it anymore,” Trump said.
