The State Department says that the review of Hillary Rodham Clinton’s emails have found as many as 305 of the messages could contain classified information requiring further review by federal agencies.

In a filing Monday as part of a lawsuit against the State Department, officials told a U.S. District Court judge in Washington they would be able to meet an existing schedule to release copies of Clinton’s emails because only about 5 percent of the messages reviewed so far contain possible secret information. The agency said those 305 emails with potential classified data were among more than 1,500 documents analyzed so far.

The filing came after Clinton contended in an Iowa radio interview that she had never sent or received any emails that had information clearly marked classified.
