Obama's second term begins

President was officially sworn in on Sunday, and will deliver his inaugural address on Monday.

On Sunday, President Barack Obama and Vice President Joe Biden were officially sworn in for a second term. Obama will deliver his inaugural address on Monday, with the ceremony expected to begin around 11:30 a.m.

The military is playing a big role in Monday's events. An escort of 2,300 military personnel -- including each service’s honor guard -- will accompany the two-to-three hour inaugural parade in the afternoon. Almost two dozen federal, state and local agencies are involved in security for the day, according to a list from Mark Knoller of CBS. They range from the Federal Aviation Administration to the Justice Department to the U.S. Park Police.
