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.
O'Connor, 82, was the only female on the bench for 12 years until 1993, when President Bill Clinton nominated Ginsburg. Ginsburg became the only female on the court in 2006, when O'Connor retired to care for her ailing husband. Sotomayor joined in 2009 and Kagan the following year.
