The U.S. Supreme Court cleared the way on Thursday for South Carolina to strip Planned Parenthood of funding under the Medicaid health insurance program in a ruling that bolsters efforts by Republican-led states to deprive the reproductive healthcare and abortion provider of public money.

The Supreme Court says states can block the country’s biggest abortion provider, Planned Parenthood, from receiving Medicaid money for health services such as contraception and cancer screenings.

Ruling says Medicaid patients cannot sue to get non-abortion health care from Planned Parenthood if states have cut off government funding for those clinics.
