Here is video of Sonia Sotomayor being sworn-in today as an Associate Justice of the Supreme Court of the United States. She will be "invested as a member of the Court" on September 8 in a special session of the Supreme Court. But the swearing-in today allows her to begin her work as an Associate Justice.
Sotomayor took the oath with her mother holding a Bible and her brother standing beside her. Chief Justice John Roberts administered the Oath, holding the text of the oath in his hands.
