When Clinton was secretary of state, Sullivan first served as her deputy chief of staff for policy and then as the director of policy planning. The interview will remain secret until it’s mentioned in a September 2016 FBI report.
The FBI determined that seven email chains containing 22 emails were sent by Sullivan to Clinton were later deemed classified at the “top secret/Special Access Program” (TP/SAP) level, which is above “top secret.”
As a result, much of the interview regards these emails. The FBI asks Sullivan to review about 14 emails he sent or received “on unclassified systems” that were later determined to contain classified information up to the TS/SAP level.
Sullivan gives some reasons why the emails may have been sent on Clinton’s unclassified server. According to the FBI, “With respect to the SAP, Sullivan stated that it was discussed on unclassified systems due to the operational tempo at that time, and State [Department] employees attempted to talk around classified information. Sullivan also indicated that, for some of the emails, information about the incidents described therein may have already appeared in news reports. … Sullivan did not recall any instances in which he felt uneasy about information conveyed on unclassified systems, nor any instances in which others expressed concerns about the handling of classified information at State.” (Federal Bureau of Investigation, 9/2/2016)
Sullivan will also give his explanation of an email in which he wanted to send her a secure fax, but the fax machine wasn’t working and she told him to “send nonsecure.”
