51-year-old Obama was sworn in for a second four-year term today by the Supreme Court Chief Justice John Roberts at the grand ceremony attended by his family, Congressmen, friends and staff and tens of thousands of people.
Obama was officially sworn in yesterday as per the constitutional requirements under which the new term of the president begins on January 20 noon.
Since this day happened to be on a Sunday when all the federal offices are closed, the ceremonial inauguration was held today; which is only for the seventh time in the US history.
