These delegates, including Huebsch, persuaded him that "The party was merely interested in the things that I was interested in, better conditions in the Screen Writers' Guild, better labor conditions in Hollywood, higher wages, and so forth, and in furthering Roosevelt's policies." Roberts left the Party in 1946, but Huebsch came back to ask him to rejoin and support the Conference of Studio Unions (CSU) strike (see "Hollywood Black Friday"). Roberts then went on the name Huebsch as a member of Communist-dominated groups in Hollywood:  On March 23, 1953, Huebsch himself appeared before HUAC, counseled by William B. Esterman. Initially, Huebsch objected to the televising of hearings by Congress, a point to which the committee acceded and rescheduled his hearing. On March 24, 1953, David A. Lang, a fellow screenwriter, named Huebsch as part of a Communist cell whose members also included: George Bassman, Nick Bela, Edward Biberman, Henry Blankfort, Laurie Blankfort, William Blowitz, Hugo Butler, Howard Dimsdale, Morton Grant, Lester Koenig, Millard Lampell, Pauline Lagerfin, Isobel Lennart, Al Levitt, Arnold Manoff, Mortimer Offner, W.L. River, Bob Robert, Marguerite Roberts, John Stanford, Wilma Shore, George Sklar, Bess Taffel, Seymour Bennett, Eunice Mindlin, and Val Burton. Lang also described a "Writers' Clinic" to which many Hollywood Ten writers belonged. On March 25, 1953, Huebsch returned for testimony, this time counseled not only by Esterman but also Daniel G. Marshall. Huebsch began by correcting the committee, saying he had not asked for no televisions but for a quashing of his subpoena. The committee disregarded his request but assured him he was not being recorded. After a short biography, the committee pressed him to state whether he had ever been a member of the Communist Party USA. Huebsch declined to answer, citing the Fifth Amendment. The committee pressed him by demanding he cite which provision of the Fifth Amendment, etc. Huebsch was equally aggressive, calling committee chairman Harold Velde "King Harold Velde" (in reference to King George III). When the committee tried to press Huebsch into strictly "yes" or "no" answers, Huebsch cited a passage in the Fifth Amendment that prohibited the committee from such.
