In a new legal development on the controversy over former Secretary of State Hillary Clinton’s emails, an appeals court on Tuesday reversed a lower court ruling and said two U.S. government agencies should have done more to recover the emails. The ruling from Judge Stephen Williams, of the U.S. Court of Appeals for the District of Columbia Circuit, revives one of a number of legal challenges involving Clinton’s handling of government emails when she was secretary of state from 2009 to 2013.
