While media coverage has focused on a half-dozen of Hillary Rodham Clinton’s personal emails containing sensitive intelligence, the total number of her private emails identified by an ongoing State Department review as having contained classified data has ballooned to 60, officials told The Washington Times.

That figure is current through the end of July and is likely to grow as officials wade through a total of 30,000 work-related emails that passed through her personal email server, officials said. The process is expected to take months.

The 60 emails are among those that have been reviewed and cleared for release under the Freedom of Information Act as part of a open-records lawsuit. Some of the emails have multiple redactions for classified information.

Among the first 60 flagged emails, nearly all contained classified secrets at the lowest level of “confidential” and one contained information at the intermediate level of “secret,” officials told the Times.

Those 60 emails do not include two emails identified in recent days by Intelligence Community Inspector General I. Charles McCullough III as containing “top-secret” information possibly derived from Pentagon satellites, drones or intercepts, which is some of the nation’s most sensitive secrets.

State officials and the intelligence community are working to resolve questions about those and other emails with possible classified information, a process that isn’t likely to be completed until January.

That will be right around the time Mrs. Clinton is slated to face voters in the Iowa caucuses in her bid for the 2016 Democratic presidential nomination.

As the number of suspect emails grows and the classification review continues, it is clear that predictions contained in a notification Mr. McCullough sent Congress this summer is likely to hold true: Mrs. Clinton’s personal emails likely contained hundreds of disclosures of classified information.
