As the Axis internal threat disintegrated under the battering HUAC investigations. the committee realistically concentrated on the "supreme" threat--oommunism. (Nearly a third of all testimony before the committee from 193848 concerned Axis subversion.) Communist infiltration of government. labor. politics. and "patriotic" organizations. as detailed by numerous witnesses. filled the headlines. The committee exposed sabotage (sitdown) strikes in Los Angeles. New York. Detroit. Chicago. Cleveland. Milwaukee. and Onglewood. The names. positions and salaries of hundreds of Federal employees identified with subversive organizations went to the Justice Department. One report. citing 160 organizations as fronts. lifted the veil of pseudopatriotism from which notorious groups as the National Council of AmericanSoviet Friendship. National Federation for Constitutional Liberties. American Youth Congress. Joint AntiFascist Refugee Committee. Civil Rights Congress. and American Youth for Democracy. Many officials of these organizations defied HUAC and were convicted of contempt.
