Planned Parenthood says at least 24 states have cut its clinics of funding since mid-2015, when anti-abortion activists released videos purporting to show group officials negotiating prices for aborted fetal tissue.

The footage gave rise to accusations that Planned Parenthood trafficked in body parts, which the group denies.

Abortion continues to be a highly contentious issue in the United States, where the procedure is legal but can be limited and regulated by individual states.

Abortion laws in Kansas are among the strictest in the United States. Last year, a Kansas judge blocked a law signed by Governor Sam Brownback, a Republican, that would have banned a common second trimester abortion procedure.

The Kansas Department of Health and Environment plans to cut Planned Parenthood off from state Medicaid funds beginning next Tuesday, according to court documents.

Planned Parenthood filed its lawsuit against Kansas on Wednesday, arguing the state will break federal law and violate the U.S. Constitution when it follows Brownback’s order to cut funding, the court records showed.

“This action challenges the unlawful, unwarranted and politically motivated decision,” the suit said.

Brownback, a Republican, has said he would ensure that no taxpayer money would go to Planned Parenthood.

By cutting funds to the organization, he wanted “to protect the unborn and support a culture of life in Kansas,” said Eileen Hawley, the governor’s spokeswoman, in an email to the Wichita Eagle newspaper published on Wednesday.

In April, federal Medicaid Director Vikki Wachino sent the letter to Medicaid agencies in all 50 U.S. states, warning them against cutting off funds to Planned Parenthood.

Wachino’s letter did not name Planned Parenthood directly, but said state Medicaid funds for healthcare providers may only be restricted if the provider cannot perform covered medical services or bill for services appropriately.
