Obama basks in Clinton's embrace

US President Barack Obama popped onstage for an unscripted appearance alongside Bill Clinton, briefly sharing the adoration being showered on the former president by Democratic delegates.

After Clinton finished a rousing speech that formally put Obama's name up for nomination, Obama walked over to give him a hug. The former president and the president shook hands, waved to the crowd, than grabbed the hands of Democrats to the side of the stage as they took their exit together - with Obama's arm on Clinton's back.
