WATCH: MSNBC’s Thomas Roberts smacks down Trump surrogate’s attempt to blame Hillary for birtherism

Trump surrogate Sarah Huckabee Sanders got asked about Donald Trump's past embrace of the birther conspiracy theory, and she tried to deflect criticism for his past statements by blaming Hillary Clinton.

Her efforts were not successful.

MSNBC host Thomas Roberts quickly slapped down Sanders's false claim that Hillary Clinton's campaign was responsible for originally questioning Barack Obama's birthplace back in 2008 during the heated Democratic primary.

"Her campaign did not ask for a birth certificate," Roberts said. "They did not question whether he was a natural born citizen. They didn't do any of that."

It goes without saying, Roberts noted, that Trump most certainly did.

"Donald Trump actually said, 'I sent investigators to Hawaii, and what they found is shocking, I'm going to reveal all of that,'" said Roberts. "He revealed nothing."

The entire time Roberts was rebutting her, Sanders could only smile and look nervously at the camera.

"I think that issue's been put to rest, I don't think anyone disputes that Barack Obama is a U.S. citizen born on American soil," she said, although it's notable that Donald Trump has never said he actually believes this, nor has he apologized ever for spreading the "birther" conspiracy.
