Halperin studied Latin American issues, and in 1935 traveled to Cuba with the [[League of American Writers]] to investigate possible [[human rights]] abuses.  Sometime during this period, Halperin joined the Communist Party of the USA (CPUSA).  In the late summer of 1941, Halperin went to work in the Office of the Coordinator of Information which later became the Research Division of the [[Office of Strategic Services]] (OSS), itself the forerunner of the [[Central Intelligence Agency]]. Halperin became head of the Latin American Research and Analysis Division and Special Assistant to the Director of the OSS, [[Duncan Lee]]. During this period, he became an espionage agent and agreed to provide intelligence for [[Joseph Stalin]]'s ruthless overseas intelligence service and secret police, the [[NKVD]].  Halperin's NKVD code name was 'Hare', and he became a member of the ''[[Golos]]'' spy network operated by the NKVD's chief of American espionage operations [[Gaik Ovakimian]].

With access to the OSS cable room, Halperin could secure copies of secret U.S. reports from any part of the world. Through the ''Golos'' spy network, Halperin provided Soviet intelligence with a large quantity of sensitive U. S. diplomatic dispatches, including reports from Ambassador John Winant in London on the position of the Polish government-in-exile towards negotiations with Stalin, Turkey's foreign policy toward Romania, the State Department's instructions to the U.S. Ambassador to Spain, the U.S. embassy in Morocco's reports on that country's government, reports on the U.S. government's relationship with Vichy and Free French factions and persons in exile, reports of peace feelers from dissident Germans passed to the Vatican, U.S. attitudes towards of Tito's [[Communist Front]] activities in Yugoslavia, and discussions between the Greek government and the United States regarding Soviet ambitions in the Balkans. Halperin also distorted OSS reports with false information in order to reflect the views of Stalin, the Soviet Union, and the Communist Party of the United States (CPUSA).

After Halperin's death, the release of the ''[[Venona project]]'' decryptions of coded Soviet cables, as well as information gleaned from Soviet KGB archives, revealed that Halperin was involved in espionage activities on behalf of the Soviet Union while serving in an official capacity with the United States government.<ref>http://www.johnearlhaynes.org/page45.html,</ref><ref>
