On August 31, 2026, the ISCAP released 38 documents from the National Archives and Records Administration. These documents, originally held within the Department of Justice, date from January 1950–July 1975, and stem from the files of Louis B. Nichols, an assistant director of the Federal Intelligence Bureau under J. Edgar Hoover. Nichols served as assistant director for 16 years between 1941–1957, with responsibilities including supervision of the FBI’s communication network and vast collection of files and records. The release of these documents marks the closure of the oldest ISCAP case, active since 2008. The ISCAP declassified some portions and affirmed the classification of others was in accordance with Executive Order 13526, section 3.3(h)(2) as 50X1 and 50X6, regarding human intelligence sources and relations with foreign governments.
Thirty of the documents, dating from 1970–1972, primarily concern telephone surveillance for the purposes of foreign intelligence and detail requests from the FBI to the Attorney General for authorization of this surveillance. A related March 1965 confidential document regards updated procedures for technical and microphone surveillance which require Attorney General approval for use and notice of discontinuance and continuance. Other documents received the same ruling of partial declassification, including a secret document containing FBI communications on the use of intelligence information in the 1950 espionage trial of Judith Coplon, inquiries regarding letters sent to President Eisenhower on a supposed World College and United States of Europe, and a memorandum detailing an inquiry to the FBI regarding a Senate employee’s alleged dismissal from the State Department for security reasons. One document, concerning recommendations for the disposition of documents in the inventory of Associate Deputy Attorney General James A. Wilderotter, was declassified in its entirety.
