Some of the seized documents detail top-secret U.S. operations so closely guarded that many senior national security officials are kept in the dark about them. Only the president, some members of his Cabinet or a near-Cabinet-level official could authorize other government officials to know details of these special-access programs, according to people familiar with the search, who spoke on the condition of anonymity to describe sensitive details of an ongoing investigation.

Documents about such highly classified operations require special clearances on a need-to-know basis, not just top-secret clearance. Some special-access programs can have as few as a couple dozen government personnel authorized to know of an operation’s existence. Records that deal with such programs are kept under lock and key, almost always in a secure compartmented information facility, with a designated control officer to keep careful tabs on their location.
