希拉里.克林顿否认曾用私人电邮发送机要信息

Democratic presidential candidate Hillary Clinton said Saturday she never used her personal email account to receive or send classified information as secretary of state.

"I am confident that I never sent nor relieved any information that was classified at the time it was sent and received," Clinton said during a campaign appearance in Iowa.

A senior official of Iowa's Republican Party said voters do not trust Clinton. He accused her of being less than truthful about what he called her "cavalier handling of sensitive information."

The U.S. Justice Department is considering an investigation into a possible compromise of sensitive information in Clinton's emails, but says it would not be a criminal probe.
