Check out this Soviet 1946 memo to Mikhail Andreevich Suslov. Ben Goldberg, an associate of Einstein, a writer for the Toronto Star, the Saint Louis Dispatch, the New York Post Today, and the New Republic was on an extended visit to the USSR. The memo says his dispatches were "extremely friendly toward the Soviet Union." While in Moscow, Goldberg was working on a book titled "England, the Opponent of Peace." Susov was a powerful figure in the USSR. He , Stalin and Kaganovich worked together during the purges. He was a member of the Presidium of the Supreme Soviet and buried next to Stalin in the Kremlin wall. That Goldberg came to Susvov's attention shows the interest Soviets took in American journalists. If Goldberg wasn't on the Soviet payroll, he could have been had he asked.

Or were they recruited or blackmailed during Nam?
