In the 1970s, the agency that provides health care to Native Americans sterilized thousands of women without their full and informed consent. Decades later, the state of New Mexico is set to investigate a little known but troubling history that haunts Native families. New Mexico legislators approved a measure this week to have state agencies examine the history, scope and continuing impacts of forced and coerced sterilization by the Indian Health Service and other providers. Outside of a 1976 U.S. Government Accountability Office report, the federal government has never acknowledged this history.
