It begins today. Obama has left the Oval Office, leaving a letter on the Resolute desk for President-elect Trump, who will lose the "elect" in a couple of hours and become the 45th President of the United States. Donald and Melania have greeted Barack and Michelle, and the crowd and the press are starting to gather in front of the Capitol Building for the inauguration ceremony. The musical performances are already underway, and the swearing-in of Trump and Mike Pence begins at 11:30 AM EST. The inaugural parade, which follows the new executive leaders from the Capitol to the White House, starts around 3 PM. 

Whether you feel it's morning again in America or the dawn of the Trumpacalypse, a great change is in the air. Watch the historic day unfold via the live stream below.
