(FORTUNE Magazine) – North Carolina Senator Jesse Helms just won't shut up, even though his , harangues on foreign policy have often embarrassed U.S. diplomats and businessmen abroad, not to mention his fellow Republicans (FORTUNE, September 15). His voice may get even louder now that the 100th Congress has convened. The ultraconservative Helms ousted moderate Indiana Senator Richard G. Lugar as the top-ranking Republican on the Senate Foreign Relations Committee.
