The FBI has not reached out to Hillary Clinton to schedule an interview over her private email server, the Democratic front-runner said in an interview Sunday.

"No. No, they haven't," Clinton told NBC News' "Meet the Press," when asked whether federal investigators had been in contact 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."

Pressed on whether the FBI probe could interfere with her path to the nomination, Clinton said she was not "concerned" about it.

"I don't think anything inappropriate was done," she said. "And so I have to let them decide how to resolve their security inquiry. But I'm not at all worried about it."

On Friday, a State Department spokesperson said it would suspend its own internal review of whether Clinton had mishandled classified information on her home-brewed email server. The State Department said the decision was made in consultation with the FBI.

"The internal review is on hold, pending completion of the FBI's work," spokeswoman Elizabeth Trudeau told reporters. "We'll reassess next steps after the FBI's work is complete."

Last week, the Los Angeles Times reported that the federal agency would begin setting up formal interviews with Clinton aides over the issue, suggesting that the investigation is entering its final stages.

In March, Clinton told CBS' "Face the Nation" that the email scandal was "moving toward a resolution" and predicted that the investigation was "getting closer and closer" to wrapping up.
