Clinton has been being accused of compromising classified information by using a personal email address hosted on a private server during her four years as the top American diplomat during the first term of President Barack Obama.
Early this week, a federal court ruled that the FBI may question her. Media reports said that the FBI was on its way to question her as part of its investigation into what is being called the "emailgate".
"No one has reached out to me yet, but, last summer, I think last August I made it clear I'm more than ready to talk to anybody anytime," Clinton said in response to a question.
"I have encouraged all of my assistants to be very forthcoming, and I hope that this is close to being wrapped up," she said.

Observing that this is a security inquiry, she asserted that she always took classified material seriously.
Clinton again acknowledged that using her personal email was a mistake by her.
"That was a mistake. I have said that. I will say it again, as often as I need to. It seemed like a convenient idea at the time that certainly wasn't. And so I always take classified material seriously. There's no argument about that that I'm aware of. And I will continue to do so, and within whatever parameters are required for the president, which I know a little bit about, having served with President Obama," she said.
