[6] Agee then worked as a case officer for the Central Intelligence Agency from 1960 to 1968, including postings to Quito, Montevideo, and Mexico City.

[6] Agee stated that by the late 1960s, his Roman Catholic social conscience had made him increasingly uncomfortable with his work, resulting in his disillusionment with the CIA and its support for authoritarian governments across Latin America.

[9] Agee's marriage to Janet was ending, and in an Inside the Company diary entry from December 1967, he wrote:The other unexpected development is a serious and deepening relationship with a woman I met on the Organizing Committee.

[11] Agee said he explained his decision from a purely personal standpoint (so as to not seem like a security risk), i.e., he had met someone, he wanted to remarry and remain in Mexico after the Olympics.

In his diary entries from October 1968—his final ones as a CIA employee—Agee condemned the Mexican government's violence against protesters, and his own complicity in the crackdown.

[13] In his 1983 book KGB Today, John Barron offered a contrasting view, stating that Agee's resignation was forced "for a variety of reasons, including his irresponsible drinking, continuous and vulgar propositioning of embassy wives, and inability to manage his finances".

The Cubans shared Agee's information with the KGB, but Kalugin continued to regret the missed opportunity to have direct access to this asset.

[19] According to Mitrokhin, while Agee was writing Inside the Company, the KGB kept in contact with him through a London correspondent of the Novosti News Agency.

[22] Vasili Mitrokhin's KGB files claim that Inside the Company: CIA Diary was "prepared by Service A, together with the Cubans".

Mitrokhin claims that Agee removed all references to CIA penetration of Latin American Communist parties from his typescript before publication at the request of Service A.

According to Mitrokhin's files, KGB headquarters assembled a team to keep the Bulletin supplied with material specifically designed to compromise the CIA.

Agee highlighted in his commentary Director of Central Intelligence William Colby's complaint that the Covert Action Information Bulletin was among the most serious problems facing the CIA.

In support of this, he adduces the relentless persecution he endured from the CIA, as it and the U.S. State Department revoked his passport and succeeded in having him deported from several Western European countries, one after the other, until he finally found refuge in Cuba.

[27][20] In a Playboy magazine interview after the book's publication, Agee said: "Millions of people all over the world had been killed or at least had their lives destroyed by the CIA ...

"[28] In the book's "Acknowledgments", he wrote: "Representatives of the Communist Party of Cuba also gave me important encouragement at a time when I doubted that I would be able to find the additional information I needed.

"[29][30] The London Evening News called Inside the Company: CIA Diary "a frightening picture of corruption, pressure, assassination and conspiracy".

"[32] The book describes how U.S. embassies in Latin America worked with right-wing death squads, and funded anti-communist student and labour movement fronts, pro-U.S. political parties and individuals.

[4] Agee helped bug the United Arab Republic code-room in Montevideo, Uruguay, with two contact microphones placed on the ceiling of the room below.

The Labour MP Stan Newens promoted a parliamentary bill, gaining the support of more than 50 of his colleagues, which called for the CIA station in London to be expelled.

[32] In 1978, Agee and a small group of his supporters began publishing the Covert Action Information Bulletin, which promoted "a worldwide campaign to destabilize the CIA through exposure of its operations and personnel".

[53] U.S. President George H. W. Bush, who considered Agee a traitor,[7] accused him of being responsible for the murder of the head of the CIA Station in Athens, Richard Welch, by the Revolutionary Organization 17 November.

[1][54] After his death, Agee's widow gathered up all of his papers from his Havana apartment and had them sent to New York University's Tamiment Library as a donation to the Robert F. Wagner Labor Archives.

According to Jonathan Stevenson, during the transport to NYU, the CIA "seized the papers, combed through all of them, and confiscated an appreciable number of documents before allowing the shipment to proceed to New York.
