(ABC News) - President Barack Obama and Vice President Joe Biden today officially embarked on their second term, taking the Constitutionally mandated oath of office in two separate private ceremonies inside their homes.
Shortly before noon in the Blue Room of the White House, Obama raised his right hand, with his left on a family Bible, reciting the oath administrated by Chief Justice John Roberts. He was surrounded by immediate family members, including first lady Michelle Obama and daughters, Malia and Sasha.
"I did it," he said to his daughters after taking the oath.
Biden was sworn in earlier today by Justice Sonia Sotomayor, the first Hispanic to administer a presidential oath, in a ceremony at his official residence at the U.S. Naval Observatory. He was joined by more than 120 guests, including cabinet members, extended family and his wife, Dr. Jill Biden.
Because Jan. 20 -- the official date for a new presidential term -- falls on a Sunday this year, organizers delayed by one day the traditional public inauguration ceremony and parade down Pennsylvania Avenue.
