Democratic presidential candidate Hillary Clinton appeared irritated on Sunday when asked whether the FBI has spoken to her about her private email server, giving only a one-word answer.
CNN's Jake Tapper posed the question to Clinton during a wide-ranging interview on his show State of the Union.
"In terms of the status of the FBI investigation into your private email server, have you been interviewed by the FBI yet?" Tapper asked Clinton.
"No," Clinton said, shaking her head.
Tapper waited for Clinton to elaborate before thanking her for coming on the show.
Clinton's answer comes as the FBI continues to investigate whether she mishandled classified information over her private email server as secretary of state.
The Washington Free Beacon reported last week that former U.S. attorneys predicted the FBI will recommend criminal charges be filed against the Democratic frontrunner, which would pose a significant obstacle to her seeking the party's nomination.
The State Department has been periodically releasing emails to the public that Clinton was obligated to hand over to the federal government by a judge.
The most recent email release reportedly shows Clinton instructing an aide to remove the heading from a document and send it non-securely to her private server if he had trouble sending it via secure fax. Some argue this was an example of the former secretary of state tampering with classified information, a point she has rejected.
