The National Right to Life Committee is indicating that it will work to unseat the anti-choice Republican House members who sidetracked a 20-week abortion ban last week because of a dispute over the wording of a rape exception.

The House members, led by Republican women including Rep. Renee Ellmers of North Carolina and Rep. Jackie Walorski of Indiana, objected to a provision that would have exempted rape survivors from the ban only if they first filed a police report describing their assault. The members contested that the provision would be politically unpopular and could discourage women from coming forward about sexual assaults. When GOP leaders cancelled a vote on the bill that had been scheduled for the anniversary of Roe v. Wade, anti-choice groups were furious, prompting Sen. Lindsey Graham to beg for their help to “find a way out of this definitional problem with rape.”

LifeNews reports that National Right to Life’s Carol Tobias recently sent an email to supporters urging them to tell Ellmers and her allies, “If you vote or work behind the scenes to allow the slaughter of abortion to continue, you will hear from pro-life voters loudly and clearly at the polls”:

In an email to supporters that LifeNews.com received titled “Elected Officials Who Betray Unborn Babies Have to Go,” Tobias said, “Last week, a small handful of congresswomen and men did something absolutely unconscionable. These lawmakers claim to be “pro-life,” and they were elected to Congress in part because they promised their constituents they would support laws to save the lives of unborn babies.” “But despite their solemn promises to their pro-life constituents and more important, to the unborn, they ganged up last week to sidetrack for now the Pain-Capable Unborn Child Protection Act. This humane bill would ban abortions when an unborn baby is developed enough feel terrible pain during an abortion – and if you can’t vote for such a humanitarian no-brainer of a law to protect the unborn, you can’t be trusted to vote for any pro-life legislation,” Tobias added. “We need to send a message loud and clear to all “pro-life” representatives who ask for our vote, but who betray the lives of vulnerable unborn babies when they get in office: If you vote or work behind the scenes to allow the slaughter of abortion to continue, you will hear from pro-life voters loudly and clearly at the polls ,” Tobias added.

Ironically, the last time the 20-week ban was being considered in Congress, NRLC was attacked by others in the anti-choice movement for being too moderate on rape exceptions.

A version of the bill approved by a House committee in 2013 had contained only an exception for abortions that would save the lives of pregnant women; GOP leaders quietly added the rape exception with the reporting requirement after the bill’s sponsor, Rep. Trent Franks, sparked controversy by implying that rape rarely results in pregnancy. When NRLC continued to support the bill, which had originally been based on its own model legislation, one of its chapters broke off and started a rival group promoting a no-exceptions policy to abortion bans.

A number of no-exceptions anti-choice groups continued to object to the most recent iteration of the 20-week ban because it contained a rape exception at all.
