Clinton says FBI has not contacted her over her use of private email server

WASHINGTON — Hillary Clinton said Sunday she has not yet been contacted by the FBI in the investigation surrounding her use of a private email server while she served as secretary of State.

"No, no, they haven't," Clinton said on NBC's Meet the Press when asked if agents had been in touch with her. "But, you know, back in August, we made clear that I'm happy to answer any questions that anybody might have. And I stand by that."

Clinton said she is not concerned that the investigation may still not be finished by the time Democrats have their national convention in July.

"No, I'm not," she told moderator Chuck Todd. "Because I don't think anything inappropriate was done. And so I have to let them decide how to resolve their security inquiry, but I'm not at all worried about it."

The Democratic front-runner acknowledged once again that sending emails from a private server while secretary of state was "a mistake."

"So let me just say again, I sent emails to government employees on their government accounts," Clinton said. "I had every reason to believe they were in the government system. It was a matter of convenience. I've said repeatedly, it was not the best choice. It was a mistake. But I think that anybody who's actually looked at this has concluded that I have now put out all of my emails. Go and ask others for their emails. Ask everybody else who's in public office. I'm the one who's done it, and I did it because I thought it was the right thing to do."

Clinton also said she's "confident" she'll debate her Democratic rival, Sen. Bernie Sanders of Vermont, before the New York primary on April 19, but would not commit to a specific date.

"I'm not the one negotiating it, that's going on between our campaigns," Clinton said.

Sanders has been pressing Clinton to debate. Sanders, a Brooklyn native, believes he has a chance to win New York while Clinton, a New York resident and former U.S. senator from the state, said she expects to carry the Empire State.

Sanders said Sunday on ABC's This Week that he also is confident that there will be a debate before the primary.

"I think we will reach an agreement," he said.
