In U.S. politics, the Hyde Amendment is a legislative provision barring the use of federal funds to pay for abortion, except to save the life of the woman, or if the pregnancy arises from incest or rape. Before the Hyde Amendment took effect in 1980, an estimated 300,000 abortions were performed annually using federal funds. The original Hyde Amendment was passed on September 30, 1976, by the House of Representatives, with a 312–93 vote to override the veto of a funding bill for the Department of Health, Education, and Welfare (HEW). It was named for its chief sponsor, Republican Congressman Henry Hyde of Illinois. The measure represented one of the first major legislative gains by the United States anti-abortion movement following the 1973 Supreme Court decision in Roe v. Wade. Congress later altered the Hyde Amendment several times. The version in force from 1981 until 1993 prohibited the use of federal funds for abortions, "except where the life of the mother would be endangered if the fetus were carried to term". On October 22, 1993, President Clinton signed into law the Departments of Labor, Health and Human Services, and Education, and Related Agencies Appropriations Act, 1994. The Act contained a new version of the Hyde Amendment that expanded the category of abortions for which federal funds are available under Medicaid to include cases of rape and incest. Background The Hyde Amendment was introduced by Illinois Republican Congressman Henry J. Hyde and first passed by Congress in 1977, four years after Roe vs. Wade. Implementation of the initial amendment was blocked for almost a year by an injunction in the McRae v. Matthews case. During this case, the Reproductive Freedom Project, the Center for Constitutional Rights, and Planned Parenthood collectively represented a pregnant Medicaid recipient and health care providers who challenged the Hyde Amendment. The United States Supreme Court vacated the injunction in August 1977, leading abortions financed by federal Medicaid to drop from 300,000 per year to a few thousand. Other bans were modeled after the Hyde Amendment, extending to other annual spending bills in the late 1970s and early 1980s. This eventually led federal funds to be banned in federal worker health plans, women in federal prisons, women in the military, peace corps volunteers, and international family planning programs that use non-U.S. funds to perform or advocate for abortion. The Hyde Amendment has been re-enacted every year since 1976,
