American  Activities Committee". As a senator (and someone who had never been  a member of the House of Representatives), McCarthy did not serve  and could never have served on HUAC. Indeed, Ms. Garfields very  words make no sense, as senators cannot be members of House  committees (or vice versa). Moreover, McCarthy had nothing  whatsoever to do with the investigations into alleged Communist  influence in Hollywood or the subsequent blacklist. McCarthy, in the  Senate, concerned himself almost entirely with alleged subversives  in government and related institutions, but he never got involved  with Hollywood or the entertainment industry, which was the  exclusive preserve of HUAC – though McCarthy certainly approved of  what that committee was doing.
