The State Department has released e-mails from the server under a court order, but said on Friday that it would withhold 22 of them because they contained “top secret” information.
Observer columnist John Schindler, a former National Security Agency analyst, said some of those e-mails contained spy names.
Clinton — whose front-running presidential campaign has been dogged by questions over her use of the unsecured home server — deleted some 30,000 e-mails she deemed personal before handing over another 30,000 to the State Department for release.
“I’ll spend the rest of my career trying to figure out what classified information was in those [deleted e-mails],” said a Pentagon counterintelligence official. “Everybody is mad as hell.
“The worst part is that Moscow and Beijing have that information, but the intelligence community maybe never will.”
