Summary  
This memorandum from Michael E. Schneberger to the Chief of Security Analysis Group details an inquiry into CIA personnel exposure related to the JFK assassination investigation. It references a P&L RYBAT cable dated 4 October 1976, which mentions Ron Casper, a Washington Post correspondent, contacting Philip B. E. Aage (likely a codename) regarding the Kennedy assassination. Casper inquired about individuals assigned to the MEPC (possibly Military Intelligence or an internal CIA unit) and sought details on surveillance capabilities and specific personnel. The document lists several CIA officers with file numbers, positions, and dates of service, noting their involvement in Mexico City Station, Trinidad, and other locations. Some were identified as having been exposed in CIA publications like "Who's Who in CIA" or AGEE’s book. A connection is suggested between Casper and Ronald Kessler, a Washington Post journalist mentioned in a security file.
