President Barack Obama Addresses the Nation

The nation's 44th president delivered a somber assessment of America's plight during his inauguration in Washington, D.C.

President Barack Obama touched on a number of topics including America's troubled economy, security, health care and education. "Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time," Obama told hundreds of thousands of people gathered on the National Mall in front of the Capitol. "But know this, America—they will be met," he said.

Wearing a navy suit and red tie, Obama was sworn in using the same Bible that was used in President Abraham Lincoln's inauguration.

As many as 2 million people were expected to crowd into the area between the Capitol, the White House and the Lincoln Memorial to hear Obama take the oath of office.
