Despite Hillary Rodham Clinton’s denials that she sent government secrets via her personal e-mail account, the State Department has already identified 60 messages containing classified info, ​according to a report.

State Department investigators found one e-mail containing classified information of an intermediate level, while the rest were at the lowest level of government confidentiality, an unnamed official told The Washington Times​ in a report published on Sunday​.

The official said it will take months for ​State Department investigators to sift through the 30,000 work e-mails sent from Clinton’s home server​.

Clinton on Saturday insisted she did not knowingly transmit classified material, and chalked up the investigations to right-wing attacks.

“I never sent classified material on my e-mail, and I never received any that was marked classified,” she said.

“The State Department has confirmed that I did not send nor receive material marked classified or send material marked classified,” the former secretary of state added.

But the chairman of the House Benghazi Committee, Rep. Trey Gowdy (R-SC), questioned on Sunday why Clinton would “triple wash” off her server personal ­e-mails that she once downplayed as talk of yoga and bridesmaids dresses.

“The more energy she put into cleansing or wiping the server clean, I think your viewers should take or infer from that, that perhaps there’s something on there she really didn’t want us to see,” he told Fox News.

Clinton did not immediately respond to a request for comment.
