The State Department has so far identified 305 emails from Hillary Clinton’s private server used while she was secretary of state to be reviewed for potentially classified information, the agency said in a court filing on Monday.
It said the emails referred for review came from a sample of about 20 percent of the Clinton emails screened to determine if they can be released publicly.
Last December, Clinton, the front-runner for the Democratic Party nomination in the 2016 presidential election, handed over about 30,000 emails she sent and received while serving as America’s top diplomat.
Clinton’s use of her private email while secretary of state from 2009 to 2013 came to light in March and drew fire from political opponents who accused her of sidestepping transparency and record-keeping laws.
The FBI was looking into the security of the federal records and classified information contained among Clinton’s emails. The U.S. government considers federal records to be government property.
