evidence: Classified information may be compartmented within a classification level. Thus, TS/SCI is information classified at the Top Secret (TS) level that is subject to the enhanced controls applicable to Sensitive Compartmented Information. For instance, TS material must either be "under the personal control of an authorized or appropriately cleared person" or "guarded or stored in a locked security container," typically a General Services Administration-approved safe. See DOJ Security Program Operation Manual at 6-202. However, SCI material must be stored in a SCIF irrespective of its classification level. According to Director of Central Intelligence Directive No. 6/9 (Nov. 18, 2002), a SCIF is a specially constructed room or other structure "intended to prevent as well as detect visual, acoustical, technical, and physical access by unauthorized persons." [...] The procedures established in the Manual, and reinforced in security briefings, provide that classified material must be either "under the personal control of an authorized or appropriately cleared person" or "guarded or stored in a locked security container," typically a General Services Administration-approved safe. However, regarding the handling of TS/SCI material, the Manual provides that "SCI information may only be... stored within a Sensitive Compartmented Information Facility (SCIF)." Further, "SCI material must not be sent to a building that does not have a SCIF or to someone who does not have access to a SCIF." As discussed above, the Manual’s requirement that SCI material be stored in a SCIF was covered in the SCI briefing Gonzales received the day he became the Attorney General.
