BBC NEWS | Americas | Obama inauguration | Obama is sworn in for second time: "Barack Obama has been sworn in as US president for the second time in two days, because one word was given out of order during Tuesday's ceremony.

The Chief Justice of the US Supreme Court, John Roberts, administered the oath again at the White House.

The decision to repeat the oath was taken out of an abundance of caution, an official said.

But Mr Obama joked: 'We decided it was so much fun....' before adding: 'We're going to do it very slowly.'"
