Leah Ward Sears wasn’t concerned two years ago, when abortion rights advocates predicted that then-Judge Brett Kavanaugh’s joining the U.S. Supreme Court would doom Roe v. Wade—but she is worried now.

Sears, who served 17 years on the Supreme Court of Georgia, including a stint as chief justice, has changed her mind as the Republican-controlled U.S. Senate stands poised to confirm Judge Amy Coney Barrett to the U.S. high court. A former clerk to the late Justice Antonin Scalia, Barrett is widely considered a vote against abortion rights, although she said in 2016, “Roe’s core holding, that women have a right to abortion, I don’t think that would change.”
