Sandra Day OâConnor: Obama Should Get to Choose Scaliaâs Replacement. Former Justice Sandra Day OâConnor said President Obama should fill the seat on the Supreme Court bench that has been vacated following the sudden death of Justice Antonin Scalia, in an interview with Arizona station FOX10 Phoenix.
The court's first female justice, Sandra Day O'Connor, was nominated by a Republican president in 1981 and was regarded as a conservative pick. The second female justice, Ruth Bader Ginsburg, was the choice of a Democratic president in 1993 and widely viewed as liberal. The two women served together until O'Connor's retirement in 2005. Ginsburg remained as the lone female justice on the Supreme Court until Sonia Sotomayor took the bench in the fall of 2009.
