"The Health Care Conscience Rights Act (H.R. 940) provides badly needed conscience protections for Americans who face an increasingly frequent use of coercive means – governmental and other – to compel participation in providing abortion and other procedures regardless of religious and moral objections. The bill would also prevent any level of government from discriminating against health care providers, including doctors, nurses, hospitals, and insurers, who decline to participate in abortions."
