Summary  
This document is a memorandum from the Central Intelligence Agency (CIA) to the Warren Commission dated March 12, 1964, detailing discussions regarding the Mexican phase of the JFK assassination investigation. The meeting focused on Oswald’s activities in Mexico City, including his visits to Cuban and Soviet embassies, which were monitored via telephone intercepts. The CIA noted that these intercepts were reviewed for U.S. security implications and shared with other agencies, though tapes were typically erased after a brief period. The Commission sought clarification on the extent of CIA records regarding Oswald’s movements between October 8 and November 22, 1963, and whether additional information existed beyond sanitized extracts. The CIA confirmed that no further substantive details were available. The document also mentions discussions about Jack Ruby, with the Commission requesting analysis of an unspecified source’s claim that Ruby had traveled to Havana in 1963 under a Czech passport. The CIA indicated limited capacity to verify such claims. A planned visit by a Warren Commission member to Mexico City was discussed to address gaps in the investigation, involving coordination with U.S. and Mexican officials.
