We are not required to release records that, as provided by FOIA, are “(a) specifically authorized under criteria established by an Executive Order to be kept secret in the interest of national defense or foreign policy and (b) are in fact properly classified pursuant to such Executive Order.” Executive Order No. 12958 (1995) (3 CFR, 1987 Comp., p. 235) provides for such classification. When the release of certain records may adversely affect U.S. relations with foreign countries, we usually consult with officials of those countries or officials of the Department of State. Also, we may on occasion have in our possession records classified by some other agency. We may refer your request for such records to the agency that classified them and notify you that we have done so.
