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.
In the summer of 2005, this speculation became newsworthy due to the announcement of the retirement of Associate Justice Sandra Day O'Connor on July 1. President Bush announced federal appellate judge John Roberts as O'Connor's replacement on July 19. On September 5, two days after the death of Chief Justice William Rehnquist, Bush renominated Roberts as the 17th Chief Justice of the United States. He was confirmed by the United States Senate on September 29, 2005.
