Gov. Josh Shapiro announced Tuesday that he is joining a coalition of states to sue the Trump administration over a provision in the “Big Beautiful Bill” that bars Planned Parenthood and other large nonprofit abortion providers from receiving Medicaid funding for a host of unrelated healthcare services.

“Today, I’m suing the Trump Administration alongside 22 other states to stop them from unlawfully defunding Planned Parenthood, which will rip away healthcare from thousands of Pennsylvanians,” he tweeted. “This unconstitutional decision threatens to close vital health care centers and deny Pennsylvanians essential, lifesaving care such as cancer screening and prevention, family planning services, and prenatal and postpartum care. As long as I’m your Governor, we will defend access to reproductive health care here in Pennsylvania.”

The states’ challenge comes one day after Planned Parenthood won a major victory in its own lawsuit over the measure in Boston, where a federal judge issued a preliminary injunction blocking the ban from taking effect against Planned Parenthood affiliates nationwide.

“Patients are likely to suffer adverse health consequences where care is disrupted or unavailable,” U.S. District Judge Indira Talwani wrote in her Monday order. “In particular, restricting Members’ ability to provide healthcare services threatens an increase in unintended pregnancies and attendant complications because of reduced access to effective contraceptives, and an increase in undiagnosed and untreated STIs.”

In her Monday order, Talwani said that the court was “not enjoining the federal government from regulating abortion and is not directing the federal government to fund elective abortions or any healthcare service not otherwise eligible for Medicaid coverage.” Instead, Talwani said that her decision would block the federal government from excluding groups like Planned Parenthood from Medicaid reimbursements when they have demonstrated a substantial likelihood of success in their legal challenge.

Federal law already prohibits the use of federal Medicaid funding to pay for abortions, but the new “defund provision” in the bill passed by Congressional Republicans earlier this month goes further. It also bars nonprofit abortion providers that generated $800,000 or more in annual Medicaid revenue in 2023 from receiving any such funding for the next year — including for services unrelated to abortion, such as annual checkups, cancer screenings, birth control and testing for sexually transmitted infections.

“We’re suing the Trump administration over this targeted attack on Planned Parenthood health centers and the patients who rely on them for care,” said Planned Parenthood’s president and CEO Alexis McGill Johnson in a statement on Monday. “This case is about making sure that patients who use Medicaid as their insurance to get birth control, cancer screenings, and STI testing and treatment can continue to do so at their local Planned Parenthood health center, and we will make that clear in court.”

California Attorney General Rob Bonta is leading the lawsuit along with the attorneys general of Connecticut and New York. Joining them are the attorneys general of Colorado, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, North Carolina, Oregon, Rhode Island, Vermont, Washington, Wisconsin and the District of Columbia.
