When Budenz later defected, he named Callen as a [[Stalinist]] infiltrator but her  SWP comrades  refused to believe him. In 1954 Callen, then known as Sylvia Doxsee and living in Chicago, was called before a grand jury. Invoking the [[Fifth Amendment]], she refused to answer questions about her membership in the SWP, her relationship with the KGB, Louis Budenz, or anything else. She was called back to another grand jury in 1958. This time she was more cooperative, confessing that she met regularly with Rabinowitz and Soble to pass on confidential Trotskyist material at an apartment rented by a woman named Lucy Booker. Callen was named as an unindicted co-conspirator when [[Robert Soblen]] was charged with espionage in 1960, but she never publicly testified.
