When Sonia Sotomayor is sworn in Saturday to the Supreme Court, she'll be able to claim two firsts: first Hispanic justice and first high court member to have her oath-taking made available to TV cameras. Sotomayor, who won a groundbreaking Senate confirmation vote Thursday over intense conservative opposition, will be sworn in twice by Chief Justice John Roberts. She will repeat one oath as prescribed by the Constitution in a private ceremony at the high court. It will be open only to members of Sotomayor's family. Then, Roberts will administer a second oath, taken by judges, with the new justice's family and friends, and reporters present.
