Some of the debate centers around specific portions of U.S. law that govern different national security activities. The U.S. military’s actions are generally governed by Title 10 of the U.S. Federal Code.

But some of the DIA’s work comes under a different portion of U.S. law, Title 50 of the U.S. Code, which generally governs covert intelligence gathering and covert action. The work of the Central Intelligence Agency and National Security Agency generally fall under Title 50, too. Some of the most sensitive Title 50 activities, especially covert actions, are conducted largely behind the scenes and require a presidential finding.
