South Dakota Republicans blocked a pro-life proposal from Gov. Kristi Noem that would ban abortions after a fetal heartbeat can be detected and was modeled after Texas’ law that allows private citizens to sue.

Republican lawmakers in the state said the bill could "jeopardize" their chances of ultimately getting abortions outlawed in the conservative state. 

Pro-life Republican House Speaker Spencer Gosch said the bill language proposed by the governor could interfere with a Planned Parenthood legal battle connected to a decade-old law forcing women to go to crisis pregnancy centers before getting an abortion. The law was halted years ago and Noem has vowed to take it to the U.S. Supreme Court

"We were not in support of the governor’s original draft language," director of South Dakota Right to Life, Dale Bartscher, said, adding that he’d like to see it return with revisions.

Noem has touted support for the bill from national anti-abortion groups.

"They’re not listening to national leaders in the pro-life movement on the momentum we have in front of the Supreme Court and what this legislation means to South Dakota," Noem told reporters of state Republicans.

She said she didn't believe her proposal "takes any credibility away from the case in front of the Supreme Court."

She tweeted earlier Wednesday: "Every single life is precious and deserving of our protection – but apparently South Dakota legislators think otherwise." 

She called the move "unprecedented" in a video message posted to social media.

"Today was the first time the legislature refused to give a hearing to a bill and they chose to do it on a pro-life issue, protecting babies." She said she had worked on the bill for months and argued the language would help build the case to overturn Roe v. Wade.
