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's 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 ' Ss 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 roduction files, operational files, : Soft files and subject files, be made available to the Commit- Oe ee as soon as possible. - The Committee further requests that AMMUG/1 CIA case £ficerslHarola Swenson) and Barney Hidalgo, FNU Langosch, and - baniel Flore§$)be made immediately available for personal inter- views with Committee staff members.
