Washington(CNN) Some of the largest anti-abortion organizations in the US are urging state lawmakers to reject legislation that would criminalize women for having abortions, saying "turning women who have abortions into criminals is not the way."
"We state unequivocally that any measure seeking to criminalize or punish women is not pro-life and we stand firmly opposed to such efforts," more than 70 national and state anti-abortion groups wrote in an open letter Thursday.
The letter's signatories include National Right to Life, Susan B. Anthony List, Americans United for Life, March for Life Action and the US Conference of Catholic Bishops.
The possibility that Roe v. Wade could be overturned has sparked fears that women who have abortions could face greater risk of criminal prosecution. Last week, Louisiana lawmakers advanced a bill that would have classified abortions as homicides, potentially allowing for women to be criminally charged for terminating their pregnancies, though most restrictive abortion bills typically exempt women from its criminal penalties or civil liability clauses.
Women have been punished under other laws, such as "fetal assault" laws, and charged with crimes that include drug use during pregnancy or self-managed abortion, according to the American College of Obstetricians and Gynecologists, which opposes the criminalization of pregnancy.
Louisiana's GOP-led state House on Thursday pared down the controversial measure to remove the bill's original language seeking to classify abortions as homicides after state anti-abortion groups opposed the bill, saying it was their "longstanding policy that abortion-vulnerable women should not be treated as criminals." The House bill is effectively dead, the amendment's Republican sponsor said.
Earlier in the week, Gov. John Bel Edwards, a rare anti-abortion Democrat, also spoke out against the bill, calling it "radical."
The national anti-abortion groups did not single out a state in their letter or mention specific legislation or policy.
Carol Tobias, president of National Right to Life, told CNN that the letter was prompted in part by the Louisiana bill and the uncertainty of what states may do in the event Roe is overturned, and also to counter the abortion rights rallies this upcoming weekend, which may point to the bill as reason to back their cause.
"We're not interested in penalizing women," she said, adding that they would want abortion providers to be held accountable.
The organizations say that if Roe is overturned, "this will be a tremendous opportunity for states to create durable policy that can stand the test of time."
"But in seizing that opportunity, we must ensure that the laws we advance to protect unborn children do not harm their mothers," they say.
They argue that women are "victims of abortion and require our compassion and support as well as ready access to counseling and social services in the days, weeks, months and years following an abortion."
In anticipation of a conservative-majority Supreme Court striking down Roe v. Wade, Republican-led states have enacted laws that restrict abortion -- 13 of which have passed so-called "trigger laws," which are abortion bans designed to go into effect once Roe is overturned.
If Roe is overturned, nearly half of all the states have laws that aim to restrict abortion access, according to an analysis by the research group the Guttmacher Institute, which supports abortion rights.
