WASHINGTON, Jan 20 (Reuters) - U.S. President Barack Obama was sworn in for a second term in office on Sunday in a small, private ceremony in the White House's Blue Room.
Chief Justice John Roberts, who leads the U.S. Supreme Court, administered the oath of office to the president, repeating a role he took in 2009, when Obama became the first black president of the United States.
Obama's swearing-in, witnessed by family, met the constitutional requirement that he take the oath on January 20. He will repeat the procedure in a public ceremony in front of the U.S. Capitol on Monday. (Reporting by Jeff Mason; Editing by Jackie Frank)
