(CNN) - NARAL Pro-Choice America, the national abortion rights group, praised Justice John Paul Stevens' record Friday and implored President Obama to nominate a replacement who will also uphold abortion rights.
"Given the current composition of the court, we will assess the eventual nominee's complete record on privacy and other relevant issues in the same way we did during Justice Sonia Sotomayor's confirmation process," NARAL President Nancy Keenan said in a statement.
"One thing is certain: opponents of women's freedom and privacy will use this vacancy on the court as an opportunity to further their attacks on nominees who have taken pro-choice positions," Keenan added. "America's pro-choice majority will fight back."
The National Organization for Women also weighed in on Stevens' retirement. The group called on the president to nominate a woman to the high court, which counts Justice Sotomayor and Justice Ruth Bader Ginsburg among its nine members.
"NOW is dedicated to achieving gender parity on the Supreme Court, and we call on President Obama to nominate a woman to fill this seat," NOW President Terry O'Neill said in a statement. "The Supreme Court is out of balance, with women making up a mere 22 percent of the bench. That's simply not enough."
