The 22 emails over seven email chains included Clinton aides Jacob Sullivan, Cheryl Mills, and William Burns, according to documents released by the State Department to Vice News Friday. 

Twenty of the emails were restricted to Clinton and Sullivan, with some originating from other unnamed State Department officials. 

Two were email chains among State officials forwarded by Sullivan — one to Clinton and Mills, and another to Clinton, Mills and Burns. 

The existence of the top-secret email chains became publicly known in January, although their recipients have remained under wraps until now. 

In his report on the investigation into Clinton’s private email server, FBI Director James Comey said that the emails were not put under stricter classification after the fact.

"Seven e-mail chains concern matters that were classified at the Top Secret/Special Access Program level when they were sent and received," Comey said. "These chains involved Secretary Clinton both sending e-mails about those matters and receiving e-mails from others about the same matters.” 

The State documents itemize each email and show who was included on the chains but do not reveal the subject of the messages. 

The documents were released in a so-called “Vaughn Index,” a response to a Freedom of Information Act (FOIA) request that withholds some information. 

Vice News said that a Vaughn Index would typically include additional insight into the content of the emails.
