Democratic presidential candidate Hillary Clinton denied that the FBI has asked to question her regarding her use of a private email server during her tenure as secretary of state.

"No. No they haven't," she said on NBC's "Meet the Press" Sunday. "But back in August we made clear that I'm happy to answer any questions that anybody might have and I stand by that."

Last week, news reports indicated that the FBI is involved in an investigation of Clinton's electronic communication practices at the state department, which critics have said demonstrated poor judgement in ensuring her communications were secure. Critics also fault her disregard for freedom of information laws and expectations of transparency.

"I've said repeatedly it was not the best choice," Clinton said of using a private server. "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 email. Ask everybody else who's in public office. I'm the one who's done it and I did it because it's the right thing to do."
