This fact sheet provides an overview of the history of the Kemp-Kasten amendment, which states that no U.S. funds may be made available to “any organization or program which, as determined by the president of the United States, supports or participates in the management of a program of coercive abortion or involuntary sterilization,” and examines its current application. Since enacted in 1985, Kemp-Kasten has often been used to withhold funding from the United Nations Population Fund (UNFPA).
