James Jesus Angleton Biography

Another important role is the ability to disseminate disinformation to foreign intelligence services in an effort to create for them a false picture of reality

The primary role of Counterintelligence is to protect agents from a foreign intelligence organization from uncovering CIA assets and operations.

Because of the nature of what was done there, Office of Security files were the most closely guarded in the Agency. It is significant that Angleton-s CI/SIG group had access to these files.

It is also significant that the Office of Security also had a file on Oswald, and was running an operation against the FPCC at the time Oswald was attaching himself that organization

The Office of Security-s primary role was to protect the CIA from harm. This involves monitoring the CIA-s own employees and assets to ensure that no one leaks data about the CIA, or betrays the CIA in any way.

Because of the nature of what was done there, Office of Security files were the most closely guarded in the Agency. It is significant that Angleton-s CI/SIG group had access to these files.

Inside this large group was a small handful of Angleton-s most trusted and closed-mouthed associates, called the Special Investigations Group (SIG)

It is also significant that the Office of Security also had a file on Oswald, and was running an operation against the FPCC at the time Oswald was attaching himself that organization.

SIG is all-important in the case of the Kennedy assassination because, for whatever reason, SIG held a 201 file on Lee Oswald prior to the assassination. Angleton-s complete counterintelligence empire employed over 200 people.

The Office of Security-s primary role was to protect the CIA from harm. This involves monitoring the CIA-s own employees and assets to ensure that no one leaks data about the CIA, or betrays the CIA in any way.

Angleton's counterintelligence staff handles CIA liaison with assassination investigators.

CIA counterintelligence liaison logged an FBI submission describing Oswald's New Orleans political activity and the Hidell identity used in FPCC material.

Angleton was also responsible for the incarceration of Yuri Nosenko, a Soviet defector who arrived in the U.S. with the seemingly unwelcome news that the KGB had had no interest in Oswald during his tenure in the Soviet Union. Angleton and other Counterintelligence officers were convinced that Nosenko was a

false defector sent by the KGB on a mission. Nosenko is locked in a small room and interrogated for more than three years, while a battle raged within the CIA over his bona fides. Because this issue was unresolved during the Warren Commission's tenure, the Commission received reports about him

CIA counterintelligence reviewed Oswald's prior Soviet defection, Mexico City contacts, and Fair Play for Cuba Committee activity during post-assassination inquiries.

CIA cover-up

Acts as a CIA counterintelligence contact for Warren Commission matters involving Oswald's foreign contacts, Mexico City material, and Soviet defector information.

A March 1964 memo notes that "Jim [Angleton] would prefer to wait out the Commission" on documents passed to the Secret Service just after the assassination, including photos of the so-called "Mexico Mystery Man." As will be seen, the Mexico City episode is replete with circumstantial evidence of a major

CIA cover-up

With Counterintelligence officer Ray Rocca as the main contact point, the CIA supplied the Warren Commission with information about Oswald and his wife Marina, their contacts in the Soviet Union, Oswald's trip to Mexico City, and more

House investigators examined CIA counterintelligence handling of Oswald and Cuba-related material as part of their assessment of agency performance.
