Last updated Apr 5, 2026|Official source

Summary

It makes it a crime to on purpose reveal the identity of a covert agent when the U.S. is actively hiding that person’s intelligence role. If someone who now or used to have authorized access to classified information that identifies a covert agent tells someone not allowed to see classified information, they can be fined under federal law (Title 18), sent to prison for up to 15 years, or both. If someone learns the agent’s identity because of their authorized access and then tells someone not allowed to know, they can be fined or jailed for up to 10 years, or both. If someone, as part of a pattern to find and expose covert agents and knowing it could harm U.S. intelligence, tells someone not allowed to know, they can be fined or jailed for up to 3 years, or both. Any jail time for these crimes must be added on to any other prison sentence the person is serving. A covert agent means an undercover intelligence officer, agent, informant, or source whose connection to the U.S. is being kept secret.
