Clinton, Obama to appear together on stage at DNC

President Obama and former President Bill Clinton will appear on stage together after Clinton's speech tonight, three Obama campaign sources tell NBC News.

Officials had put out word that the Time Warner Arena was "at capacity." But NBC reported that the president would be making an appearance in the arena.

Portions of the hall were shut off, and NBC reporters spotted a motorcade heading to the arena, which was likely for former President Clinton.
