President Barack Obama officially begins his second term today, a day ahead of his public swearing in and all the pomp and ceremony of a U.S. presidential inauguration. Because the Constitution calls for the president to be sworn in on January 20, Obama and Vice President Joe Biden will be sworn in for their second terms in relatively quiet ceremonies before they take their public oaths in front of the Capitol on Monday and before an audience spread down the National Mall. Obama's Monday address will lay out the values and vision for his second term. He will also details policy in his February 12 State of the Union address, according to a report of CNN.
