In 1981, the United Nations announced that 1985 would be an International Youth Year (IYY). USYC attempted to take the lead in planning for U.S. participation in the IYY. Competition with a rival body, the U.S. Committee on International Youth Year, led to a congressional investigation. In 1985, Congress passed the Zorinsky amendment (U.S.C. 1461-1a), which barred programs funded by the USIA from operating domestically or conducting propaganda campaigns against domestic audiences. The law also required the IYY committees to be representative and open to all youth organizations. USYC refused to open the executive positions on its IYY committee to other groups, and American participation in the IYY collapsed.
