In case of classified information being disclosed, which agency must the DoD report to?

When classified information is disclosed, the Department of Defense (DoD) is required to report such incidents to the Federal Bureau of Investigation (FBI). The FBI is the primary agency responsible for investigating national security threats, including those related to the unauthorized disclosure of classified information. This requirement ensures that sensitive national security information is protected and that any potential insider threat or leak is thoroughly investigated.

The FBI has the expertise and resources to handle cases involving classified information and can coordinate with other intelligence and law enforcement agencies as necessary. Their role in this context emphasizes the importance of protecting national security interests and taking appropriate action when classified information is compromised.

In contrast, other agencies listed, while important in their respective roles, do not have the primary responsibility for managing and investigating cases of disclosed classified information. The Department of Justice, for example, typically handles the prosecution of such cases after they have been investigated, and the Department of Homeland Security focuses on threats to domestic security rather than specific insider threats related to classified information. The National Security Agency, meanwhile, is more focused on signals intelligence and cyber operations rather than the direct investigation of information leaks.
