Tonight, Anderson will be counting down to Barack Obama's inauguration live from the National Mall in Washington, D.C. We're almost 14 hours away from the historic swearing-in of this nation's 44th President.
It's been a busy night in the nation's capital. Just moments ago, President-elect Obama paid tribute to Sen. John McCain at a bipartisan dinner at the Hilton Hotel. McCain is not being left out of the limelight, even though he lost the November election.
During Obama's speech tonight he poked fun at their months on the campaign trail together.
"I'm here tonight to say a few words about an American hero I have come to know very well and admire very much - Sen. John McCain," Obama said as he opened his speech. "And then, according to the rules agreed to by both parties, John will have approximately 30 seconds to make a rebuttal."
Then Obama changed his tone and called for bipartisan cooperation during his presidency.
"We will not always agree on everything in the months to come, and we will have our share of arguments and debates," Obama said. "But let us strive always to find that common ground, and to defend together those common ideals, for it is the only way we can meet the very big and very serious challenges that we face right now."
Do you think that can happen in Washington?
We'd love to hear your thoughts.
Meanwhile, Michelle Obama hosted an inaugural concert tonight for children at the Verizon Center in Washington.
The Obama girls, Malia and Sasha, were on hand to watch the Jonas Brothers, Miley Cyrus and others take the stage. The event was in honor of U.S. military families around the world.
We'll have more on tonight's events, and look ahead to tomorrow on AC360°.
