WASHINGTON, April 3 (UPI) -- Democratic presidential front-runner Hillary Clinton, appearing Sunday on NBC's Meet the Press, sought to tamp down what is becoming an increasingly testy race with Vermont Sen. Bernie Sanders for the party's nomination.
Clinton was captured scolding a Sanders supporter who questioned her on a rope line about accepting campaign donations from the fossil fuel industry. Clinton responded to the young woman by pointing a finger in her face and angrily saying "I'm so sick of the Sanders campaign lying about me."
Asked Sunday whether there were other incidents where Sanders has "lied" about Clinton's record, the former secretary of state showed her diplomatic side.
"Well, I'm not, you know, I'm not going to go into that. I think that we've tried to run a campaign on the issues. I'm going to keep talking about the issues," she said.
Additionally in the interview, Clinton said she has not been contacted by the FBI regarding their investigation into her use of a private email server while she was at the State Department. Critics have assailed her for potentially mishandling classified government documents, though Clinton has said no classified documents were ever mishandled. The State Department has identified 22 emails out of thousands over her time there that have been deemed classified during the course of the investigation. Clinton has maintained those classifications were decided after the fact, and were not in place at the time she sent or received the information.
The FBI is investigating whether Clinton or any of her top aides at the State Department broke the law in how they handled sensitive government information. That investigation is reportedly wrapping up, and is likely to conclude with in-person interviews of Clinton and several of her top aides before the Justice Department decides whether to file charges against anyone.
Clinton on Sunday reiterated her willingness to speak to the FBI, saying she would be "happy" to answer any questions.
