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 1957, she returned to the United States, settled in Arizona with her husband, and created a private practice with another attorney. Eight years later, she began working as the Assistant Attorney General of Arizona. In 1969, Sandra Day OâConnor was appointed to the Arizona State Senate to fill a vacated seat. In 1970, she kept that seat when she was elected to the State Senate for a full term as a Republican. She was reelected to that position twice, even serving as the first female majority leader in any state senate.
