Hillary Clinton Jokes About Wiping Email Server 'With A Cloth Or Something'

— -- Hillary Clinton joked to reporters Tuesday in Las Vegas about whether she "wiped" her email server clean before giving it to the FBI.

“What? Like with a cloth or something?” she asked, then laughed. “I don’t know how it works digitally at all.”

Clinton maintained that she has turned over the server to investigators and gave them "every single thing" that was work-related. Federal investigators are looking into the security of the server and whether there was classified information in the emails from the private account she used while serving as secretary of state.

She made the quip during an exchange with Fox News’ Ed Henry.

This isn’t the first time Clinton has joked about her emails: the former Secretary of State also quipped about why she liked Snapchat at the Wing Ding Dinner in Iowa.

“You may have seen that I recently launched a Snapchat account,” she said. “I love it. Those messages disappear all by themselves.”

Clinton turned over more than 30,000 personal messages from her email server to the State Department, which is being released in batches. And earlier this month, Clinton turned over her private email server to the Department of Justice.

The Intelligence Community's inspector general had notified senior members of Congress that two emails randomly sampled from Clinton's server contained sensitive information that was later given a "Top Secret" classification, while two others contained classified information at the time they were sent.

The emails with information subsequently classified as "Top Secret" were forwarded to Clinton, according to the State Department.

Just this week, Intelligence community officials involved in the review of Clinton’s emails flagged 305 messages for further inspection, new court documents released Monday said.

Clinton has maintained that she never used her private email to handle classified information. Her spokesman, Nick Merrill, said it was “not surprising” that several hundred messages were flagged for further inspection “given the sheer volume of intelligence community lawyers now involved in the review of these emails.”

"We expect there will continue to be competing assessments among the various agencies about what should and shouldn't be redacted,” Merrill said in a statement to ABC News.
