The Supreme Court will hear arguments in a South Carolina case over whether states can cut off Medicaid funding to Planned Parenthood. Medicaid money generally can't be used for abortions, but the group is a key provider of other reproductive health services for patients using the publicly funded insurance. If South Carolina wins, more states could also block the group from Medicaid money as part of a wider push to defund Planned Parenthood after the Supreme Court decision overturning nationwide abortion rights. The Trump administration is joining South Carolina for Wednesday's arguments before the high court.
