WASHINGTON (CNN) — Vice President Joe Biden was sworn in to begin his second term of office Sunday, hours before President Barack Obama will do the same.
The ceremonies are taking place quietly, a day before Obama and Biden take their public oaths in front of the Capitol before a crowd on the National Mall.
The Constitution calls for the president to be sworn in on January 20.
Biden took his official oath shortly after 8 a.m. at the Naval Observatory, his official residence. Supreme Court Justice Sonia Sotomayor administered the oath. With his hand on a family bible, Biden vowed to support and defend the Constitution.
Obama’s oath is scheduled to take place at the White House shortly before noon.
