House of Representatives 3331 HOUSE OFFICE BUILDING, ANNEX 2 WASHINGTON, D.C, 20515 July 13, 1978 COMMITTEE SENSITIVE Office of Legislative Counsel Central Intelligence Agency Washington, D. C. 20505 Dear Mr. Breckinridge: I write in reference to the Committee's requests of 6 June 1978 and 8 June 1978 that the Central Intelligence Agency make available for review by Committee staff members all files and index references to the following individuals: Luisa Calderon AMMUG/1 During the week of 2 July 1978, various files concerning the above-named individuals were made available for review to Charles Berk of this Committee. Mr. Berk has now reviewed Luisa Calderon's 201 file and AMMUG/1's Office of Security file, Office of Personnel file, and Volumes One and Two of AMMUG/I1's 201 file covering the period 25 April 1964 - October 1965. After a careful review of these materials, it has been determined that CIA-originated reports of 5 May 1964, 6 May 1964, 7 May 1964, 8 May 1964, 11 May 1964, and 19 June 1964, each based upon AMMUG/1's knowledge, are absent from the materials provided to Mr. Berk. Furthermore, neither notes nor memoranda upon which these reports may have been based are present in the files. The content of these reports, notes and memoranda are of substantial interest to the Committee. It has also been determined that AMMUG/1 material now stored by the CIA at its Warrenton, Virginia facility has not been made fully available to the Committee. This omission came to Mr. Berk's attention inadvertently during a conversation that he had with Chris Hopkins. Mr. Berk's review of a 1 May 1964 CIA-originated dis- patch also indicates that at least twenty-two. reels of tape HW 53060 Docld:32272712 Page 2?
HW 53060 Mr. Scott Breckinridge July 13, 1978 Page 2, 1978 COMMITTEE SENSITIVE recorded interviews conducted by CIA representatives with AMMUG/1 are absent from the files provided thus far to the Committee. These twenty-two reels of tape recordings were listed as attachments to the above-referenced CIA dispatch. The actual interviews from which the tape recordings were generated were conducted shortly after AMMUG/1's defection from the Cuban Intelligence Service. Furthermore, three trans- scripts of tape recorded CIA interviews with AMMUG/1 are absent from the files thus far provided to the Committee. These transcripts were listed as attachments to a CIA-originated re- port of 30 April 1964. The actual interviews upon which the transcripts are based were also conducted shortly after AMMUG/1 defection from the Cuban Intelligence Service. In the case of Luisa Calderon's CIA files, CIA informa- tional reports, cables, and dispatches referenced to in her 201 file have been found to be absent from that file. In addition, a CIA transcript of a telephone conversation in which she par- ticipated on the day of President Kennedy's assassination is absent from her 201 file. / The absence of these reports, notes, memoranda, and other material from the AMMUG/1 files and the Luisa Calderon files reviewed to date may be an indication that other related materials have not yet been made available to the Committee for review. The Committee therefore reiterates its request that all files and index references on Luisa Calderon and AMMUG/1, in- cluding but not limited to production files, operational files, soft files and subject files, be made available to the Commit- tee as soon as possible. The Committee further requests that AMMUG/1 CIA case officers Harold Swenson, and Barney Hidalgo, FNU.Langosch, and Daniel Flores be made immediately available for personal inter- views with Committee staff members. As some of the matters discussed herein may be of a sensitive or classified nature, this communication may require appropriate classification. Thank you for your continued cooperation. Sincerely, GRB:cbd DoclIda: 32272712 Page 3
