Executive Order 13142
Amendment To Executive Order 12958-Classified National Security Information
This executive order amends Executive Order 12958 to extend automatic declassification deadlines for classified national security records over 25 years old, creating staggered timelines (6.5 years, 8 years, and 25 years from information origin) based on record complexity and sensitivity. It also formally establishes the Information Security Oversight Office (ISOO) within the National Archives and Records Administration, granting it binding directive authority and on-site review powers over agency classification programs.
