Barack Obama Sworn In For Second Term As U.S President.

Barack Obama has been sworn in for a second term as President of the United States of America in a private White House ceremony.

Mr Obama was officially sworn in at a very brief ceremony in the Blue Room of the White House, taking the oath from Chief Justice John Roberts using his wife Michelle's family bible.

He will be sworn in again at a time-honoured public ceremony at the Capitol in Washington on Monday.

Honoring tradition, Joe Biden, the vice-president, was sworn in before his boss at an early morning ceremony at his official residence, before the two laid a wreath at the Tomb of the Unknowns at Arlington National Ceremony.

Supreme Court Justice Sonia Sotomayor - picked by Mr Obama to be the first Hispanic judge to sit on the High Court in his first term - made her own slice of history by leading Biden as he took the oath.

Chief Justice Roberts was able to avoid a repeat of 2009 when he stumbled over the oath, prompting the White House to request a redo the following day.
