Summary:  
The document details a response from the National Security Agency (NSA) to the Assassination Records Review Board (ARRB) regarding NSA's capabilities and records related to Cuba and Mexico City during 1963–1964. It notes that NSA had significant COMINT (Communications Intelligence) capabilities against Cuba, including intercepting communications between Havana and Mexico City. However, no records directly linking these activities to the JFK assassination were found beyond those already provided to the ARRB. The NSA mentions a former employee, Johnny Johnson, who may have specific knowledge of operations involving Cuban targets. Additionally, the NSA states it has 12 boxes of Mexican diplomatic communications but confirms no new information about the assassination was uncovered. The document also references interactions with an INSCOM historian and Frederick Berghoff, a former NSA official, for recollections on NSA activities in Mexico during the early 1960s. No specific targeting of Soviet assets in Mexico City or COMINT tasking related to Mexican communications is identified.
