Biden in tears after Obama surprise

Barack Obama awarded Vice President Joe Biden America's highest civilian honor on Thursday, in an emotional surprise ceremony at the White House.

In remarks billed as a joint farewell to family, friends and staff before they leave the White House next week, Obama described Biden as "the finest vice-president we have ever seen" and a "lion of American history."

"So, Joe, for your faith in your fellow Americans, for your love of country, and for your lifetime of service that will endure through the generations. ... For the final time as president, I am pleased to award our nation's highest civilian honor, the presidential medal of freedom."

Biden's jaw dropped, he rolled his head back and turned his face away from the audience to wipe away the tears.

After composing himself and receiving the medal, Biden stepped up to the dais and looked around the room in search of his chief of staff -- and fired him, in jest, for not giving him early warning.

"I had no inkling," Biden said.

"Mr President, I'm indebted to you. I'm indebted to your friendship. I'm indebted to your family," he said.
