Planned Parenthood and blue states challenge congressional legislation defunding abortion providers as unconstitutional bill of attainder in federal court.

More than 20 mostly Democratic-led states sued the Trump administration Tuesday over its efforts to cut Medicaid payments to the nation's largest abortion provider — Planned Parenthood. The move comes in response to the package of tax breaks and spending cuts Trump signed earlier this month.

A federal judge recently ruled that a Republican effort to withhold Medicaid funds from the organization’s clinics was likely unconstitutional.
