More than 300 emails from Hillary Clinton’s private server are to be reviewed to see if they contain classified information. The US State Department identified the emails as it carries out its check on wether they can be released publicly. Mrs Clinton’s use of private email while secretary of state for four years has sparked a barrage of criticism. The Democratic 2016 frontrunner says her private email contained nothing that was classified at the time. Critics say her set up was unsecure, against government rules and designed to shield her communications from oversight. Last December, she handed over 30,000 emails she sent and received while in office. A team of officials has been checking the emails since a federal judge ordered they be released to the public on a rolling basis over the next five months. In court papers filed with a US district court judge in Washington on Monday, the State Department updated it’s progress. One of its officials told the court that 305 of her emails are being recommended for review by intelligence agencies. The FBI is investigating wether classified information was improperly sent via the server and stored there.
