“Oswald was under counterintelligence surveillance from 1959 to 1963,” Morley said. “Everywhere he went he touched CIA collection operations, code-named secret intelligence operations, whose product was delivered to [counterintelligence chie James] Angleton.”
This may sound exaggerated or controversial so interested readers should consult the original records for confirmation.
The code name operations that collected intelligence on Oswald were HTLINGUAL, AMSPELL, and LIENVOY.
Jeff you leave out LIFEAT, the other telephone tap operation (I believe this was more targeted to the Soviets ) was running at the same time as LIENVOY, and as I recall it also collected info on Oswald.
