US President Barack Obama has said that it was through news reports that he first learned that Hillary Rodham Clinton used a private, nongovernment email account while serving as his Secretary of State. In an interview with CBS News, Obama says he’s glad that Clinton has instructed that those emails about official business be disclosed. Clinton, the leading Democratic contender in the 2016 presidential campaign, has drawn criticism for using a private server during the four years she was the nation’s top diplomat.
