The reproductive health giant has estimated that the defunding could force about 200 of their clinics to shutter

Planned Parenthood sued the Trump administration on Monday over a provision in Donald Trump’s sweeping domestic policy bill that would strip funding from health centers operated by the reproductive healthcare and abortion provider.

In a complaint filed in Boston federal court, Planned Parenthood said the provision was unconstitutional, and its clear purpose is to prevent its nearly 600 health centers from receiving Medicaid reimbursements.

Planned Parenthood said that would have “catastrophic consequences”, given that the health centers serve more than 1 million patients annually through Medicaid, the US government’s insurance program for low-income people. More than 80 million people use Medicaid.
