“ Also, while no written record has been located in Bureau files to verify this it has been stated by NSA officials that during the war Soviet diplomats in the U.S. were granted permission to use Army radio facilities at the Pentagon to send messages to Moscow. It has been stated that President Roosevelt granted this permission and accompanied it with the promise to the Soviets that their messages would not be intercepted or interfered with by U.S. authorities. Here, again, the Soviets would vilify the U.S. as an unfaithful ally and false friend. ”

“ Continuous research through Bureau files is being conducted to identify other agents and we are alert to the need of capitalizing on the information available to us to penetrate any presently operating Soviet espionage network. ”

“ The information can then be given only to one cleared to receive communications intelligence material. Very few people in the Government are so cleared.
III.⁠ NATURE OF MESSAGES AND USE OF COVER NAMES
The messages furnishes the Bureau are, for the most part, very fragmentary and full of gaps. Some parts of the messages can never be recovered again because during the actual intercept the complete message was not obtained. Other portions can be recovered only through the skill of the cryptographers and with the Bureau's assistance. ”

“ In the Laucklin Currie case when we considered the possibilities of prosecution, General Canine of NSA indicated it would be highly inadvisable to reveal U.S. efforts to break the Russian code. It is believed that NSA would strongly object to any attempt to use information in court since to do so would reveal to the Soviets the degree of success the U.S. had in breaking the Soviet code which was used during 1943–46. ”

“ These factors weigh heavily against using information for prosecution.
Based on information developed from traffic, there has been prosecution of Judith Coplon, Valentin Gubitchev, Emil Klaus Fuchs, Harry Gold, Alfred Dean Slack, Abraham Brothman, Miriam Moskowitz, David Greenglass, Julius and Ethel Rosenberg, Morton Sobell and William Perl. All of these cases were investigations instituted by us directly or indirectly from information. These prosecutions were instituted without using information in court. ”

“ Paige will be contacting the Bureau regarding this matter. It is felt that we should continue to maintain the position that AFSA is the only agency which can disseminate the actual information. It is felt we should limit any discussion with CIA to cases where they have a definite responsibility, such as MGB agents now abroad, former OSS personnel, and the like. ”

“ Dissemination of communications intelligence material is made on a "need-to-know" basis and the material has been restricted even more so than other communications intelligence data since it has not been published or distributed to USCIB consumers, other than the FBI and, more recently, CIA. Before any decision could be made on using information in court the messages would have to be declassified. ”

“ The other individual was Guy Burgess. The two men disappeared just prior to the time that MacLean would have been identified as a Soviet agent on the basis of the information. There is some indication that Harold Adrian Philby, former MI6 representative in the U. S., may have tipped off the two men concerning the investigation. CIA has been considerably alarmed over this case because of the close relationship which existed between their office and Philby. We previously had a discussion with Harvey concerning this investigation. ”

“ In addition to the individuals mentioned heretofore who were MGB agents attached to official establishments, there is a considerable number that we have not identified to date and there are others who occupied relatively minor positions who have been identified. ”

“ He is also identified as such by material from , and the latter source has supplied considerable information relative to his activities in the U. S. CIA is already cognizant of his identity as a Soviet agent. Katz has been out of the U. S. since 1948; from the latter date until about mid-1951 he was principally in France; since then he is believed to have been in Israel. CIA has conducted investigation of Katz in France, and has been asked to conduct investigation in Israel. ”

“ It is noted that the is also brought up to date at the same time annually and includes substantially the same information included in this summary and appendix with the exception of the cover names. This summary includes 10 additional identifications made during the past year. Our experience has shown that the information being obtained from [Venona project] is diminishing and it is anticipated that additional identification will be made less frequently than in the past. ”

“ After the death of Golos in 1943, two meetings were arranged with this group in 1944. The first meeting was arranged by Browder and is believed to have been held on 2/27/44. The meetings were held in the apartment of John Abt in NYC and Bentley was introduced to four individuals identified as Victor Perlo, Charles Kramer, Harry Magdoff and Edward Fitzgerald. ”

“ This requires painstaking effort by experienced cryptographers who can also translate Russian. Both and work on this problem and work sheets have been made up by and sent to . Also, has a man in England working with . In turn, have a cryptographer working full-time at .
The first report received by the Bureau on MGB deciphered traffic was received from Army Security Agency (predecessor of NSA) 4/16/48. Colonel L.E. Forney, Intelligence Division of the Army, advised at that time that the messages given to the Bureau were dated 1944 but the decodes had just been accomplished. Col. ”

“ He said he recognized full well that the FBI had the prime interest in this material by reason of the fact that it was primarily domestic in nature. He stated, however, that a considerable amount of it dealt with fromer employees of OSS and inasmuch as CIA has a large number of former OSS employees on their staff, that they felt that they have a definite interest in this material. Mr. ”
