Event Details

This document appears to be a historical overview of United States signals intelligence, tracing its origins from the 'Black Chamber' and Western Union cooperation in the 1920s through World War II codebreaking (Enigma and Purple ciphers) to the formation of the NSA in 1952. It details the NSA's mandate to protect US communications and intercept foreign signals, noting its expansion during the Cold War with a 'black budget' and advanced technology. While part of a larger House Oversight production (likely related to intelligence abuses or history), this specific page contains no direct references to Jeffrey Epstein.
