In 1995, the CIA and the NSA for the first time made public the existence of the World War II Venona project, which, beginning in 1943, had decrypted or partially decrypted thousands of telegrams sent from 1940 to 1948 to the primary Soviet foreign intelligence agency—for most of that period, the NKVD—by its U.S. operatives. Although known to the FBI, Venona had been kept secret even from President Truman. One cable, Venona #1822, mentioned a Soviet spy codenamed "ALES" who worked with a group of "Neighbors"—members of another Soviet intelligence organization, such as the military's GRU. FBI Special Agent Robert J. Lamphere, who supervised the FBI's spy chasing squad, concluded that the codename "ALES" was "probably Alger Hiss".
