Under what circumstances may classified information be shared with other agencies?

Sharing classified information with other agencies is permissible when authorized by the originating agency. This authority ensures that sensitive information is handled appropriately and that the sharing aligns with national security policies and procedures. The originating agency, which created or possesses the information, has the responsibility to determine how and when that information can be disseminated, including to other governmental or military entities.

This principle upholds the need for oversight and control over classified materials, allowing for the necessary collaboration between agencies while maintaining the integrity and security of the information. Collaboration on intelligence, operations, and other defense-related activities often requires sharing information, but it must be done within the confines of regulations set by the originating agency.

The other choices are not valid in the context of sharing classified information. Specific mission requirements may dictate some aspects of information-sharing, but ultimate approval still lies with the originating agency. The notion that sharing is never allowed is incorrect, as inter-agency cooperation is essential for effective national defense. Lastly, if information is classified as public information, it would no longer be classified, and therefore the framework for sharing would differ fundamentally.
