Vice President Joe Biden was sworn in for his second term on Sunday.
Supreme Court Justice Sonia Sotomayor administered the oath of office to Biden in the Naval Observatory, the vice president’s official residence.
"It's an incredible honor to have Associate Justice Sonia Sotomayor swear me in," Biden said in a statement. "I believed strongly that she would make a great Justice, and it was one of the greatest pleasures of my career to be involved in her selection to the Court. From the first time I met her, I was impressed by Justice Sotomayor's commitment to justice and opportunity for all Americans, and she continues to exemplify those values today. Above all, I'm happy for the chance to be sworn in by a friend - and someone I know will continue to do great things."
After the short swearing-in, Biden again thanked Sotomayor personally, explaining to the small group of guests the reason for the early timing of the event.
Biden took the oath on a family Bible bearing a Celtic cross. It has been in the Biden family since 1893.
