She becomes the 112th justice and the fourth woman ever to serve on the Supreme Court. Chief Justice John Roberts administered the oath to Kagan in a ceremony at the court.
Elena Kagan became the nation's newest U.S. Supreme Court justice Saturday, amid cheers from family of friends as she completed her oath of office.
Kagan, 50, becomes only the fourth woman to serve on the nation's highest court. For the first time in history, the nine-member body will have three female justices sitting on the bench.
"I, Elena Kagan, do solemnly swear that I will administer justice without respect to persons, and do equal right to the poor and to the rich," Kagan began. She repeated the lines after Chief Justice John Roberts, who administered the second of two oaths, her left hand placed on a Bible belonging to Justice Stephen Breyer.
When she finished, she clasped her hands and grinned as friends and family erupted in a standing ovation. Among those attending the ceremony in the marbled building were Kagan's two brothers and retired Justice John Paul Stevens, whom she replaces. Current justices Clarence Thomas, Ruth Bader Ginsburg and Sonia Sotomayor also were there. She'll join them after Oct. 1, when she's formally seated on the court.
Kagan was confirmed Thursday by the U.S. Senate on a 63 to 37 mostly partisan vote. Many Republicans who voted against her sited her lack of judicial experience, among other issues. Five Republicans broke party ranks to support her. Only one Democrat, Sen. Ben Nelson of Nebraska, voted against her.
Kagan becomes the 112th U.S. Supreme Court justice. Her appointment is not expected to change the court's current philosophical balance.
