"Roberts actually swore in Kagan twice. She recited one oath as prescribed by the Constitution during a private ceremony in a conference room at the court with only her family present. 

Roberts then administered a second oath, taken by judges, with Kagan's family and friends, including her brothers Marc and Irving, and reporters present. Also in attendance were Justices Anthony Kennedy, Clarence Thomas, Ruth Bader Ginsburg and Sonia Sotomayor."

WHY TWICE?  (AGAIN?  ONLY BO's PEOPLE?)
