The HUAC (House Un-American Committee) was Sen. Joseph McCarthy's favorite organization from the 1950's to root out Communists in Hollywood and elsewhere. There has been a move to rehabilitate McCarthy's image as a fighter for the American way.
Now Rep. Steve King (R-IA) want's to bring back that era. In 2008 Michelle Bachmann argued for a similar "witch hunt" to root out those 'anti-Americans' in the government including Obama so this is not an entirely new concept.
Hunting down commies is just what we need right now.
