This year’s inauguration turnout isn’t expected to be quite as large as four years ago. YNN's Erin Billups has a look back at the 2009 Presidential Inauguration.

People are already flooding the National Mall to witness President Obama’s swearing in and inaugural address Monday.

The president officially took the oath for his second term in office Sunday in front of a small group. Chief Justice John Roberts administered the oath in the Blue Room of the White House. Only a small group of people, including the president's daughters and wife, were in attendance for the ceremony.

The president used his wife's family Bible for the ceremony. The Bible once belonged to the Michelle Obama’s grandmother.

Keeping with tradition, the First Family attended a morning church service Monday before the festivities.

President Obama, Vice President Biden and their families attended service at St. John's Episcopal Church across from the White House.
