NARAL Pro-Choice American, one of the nation's largest abortion rights group, endorsed Supreme Court justice nominee Sonia Sotomayor Tuesday.
The group withheld its support of Sotomayor for months, citing uncertainty of her views on abortion rights.
NARAL claimed that during her confirmation hearings last week, Sotomayor showed strong support of privacy rights, which include a woman's right to choose.
"We are pleased that Judge Sotomayor expressed stronger support for the established constitutional right to privacy than either Chief Justice Roberts or Justice Alito, both of whom had anti-choice records before being nominated to their current positions," Nancy Keenan, the group's president, and Kelli Conlin, the head of its New York chapter, said in a joint statement.
GOP support of Sotomayor has also grown, although many are still reluctant.
Sen. Susan Collins of Maine is now the fourth Republican to publicly support the judge and break party lines.
"I know that I will not agree with every decision Justice Sotomayor reaches on the court, just as I disagree with some of her previous decisions," Collins said in a statement.
Collins added that she believes Sotomayor "understands the proper rule of a judge and is committed to applying the law impartially without bias or favoritism."
The judiciary committee will vote on Sotomayor July 28.
