Summary

It makes it a crime for anyone who, on purpose and knowing the material is classified, shares or publishes certain secret information with people who are not allowed to have it, or uses that information in a way that harms U.S. safety or helps a foreign government. The rule covers secret details about codes and secret-writing methods, the design and use of devices for cryptography or signal intelligence, the United States’ or a foreign government’s communication‑intelligence activities, and information gotten by intercepting a foreign government’s communications. Giving such information to a proper committee of the U.S. House or Senate when they lawfully ask for it is allowed. Defined terms (one line each): classified information — information marked for limited distribution for national security; code/cipher/cryptographic system — any secret-writing method or device; foreign government — any group or person acting for a foreign state or claiming to act as one; communication intelligence — methods of intercepting others’ communications; unauthorized person — anyone not allowed to receive the listed information. A person convicted must forfeit money gained from the offense and any property used to commit it. The court must order the forfeiture. The federal forfeiture rules in 21 U.S.C. 853(b), (c), and (e)–(p) apply, and leftover forfeiture money after costs goes to the Crime Victims Fund (42 U.S.C. 10601). “State” includes the States, D.C., Puerto Rico, and U.S. territories.
