In 1995 the National Security Agency (NSA) published documents from the Venona Project (1943–80), a counter-intelligence program for the collection and decryption of KGB and GRU telegraph messages, collected from 1943 to 1980. On September 13, 1944, the KGB station in New York City transmitted a message to Moscow that Vladimir Pravdin, an NKVD officer working undercover as a reporter for TASS (the Telegraph Agency of the Soviet Union), had sought to communicate with a Soviet agent code-named BLIN, in Washington, DC, but that BLIN had been avoiding a meeting with Pravdin, claiming that his work schedule did not permit the requested meeting. He reported that Samuel Krafsur, an American NKVD agent codenamed IDE, who worked for TASS in the building that housed Stone's office, had tried to "sound him out, but BLIN did not react."
