Reuben Borough is seated on the left; he was the party's candidate for U.S. Senate from California in 1952. Robert W. Kenny, attorney general of California from 1943-47 and counsel for the Hollywood Ten, is seated between the speaker and Bass; progressive attorney Dan Marshall is seated on the right, smoking a cigarette. IPP was formed on June 15, 1948, when the Progressive Citizens of America, Southern California chapter, merged with the Independent Progressive Party of California.
