WASHINGTON--Mayor Rahm Emanuel--President Barack Obama's former chief of staff-- will speak at the 2012 Democratic National Convention--one of a string of high profile Democrats getting the spotlight in Charlotte. The convention committee is starting to roll-out the speakers, on Monday officially announcing former President Bill Clinton will deliver the prime-time nominating address on Wednesday Sept. 5.

Massachusetts Democratic Senate candidate Elizabeth Warren gets a high-profile speaking assignment--she will speak before Clinton--in order to boost her race against Sen. Scott Brown (R-Mass.)

Biden will speak at the Bank of America stadium Sept. 6 before Obama accepts his second nomination. Clinton commands the stage at the Time Warner Cable Arena.

The download from the Obama team: "The VP will speak Thursday because that night is the focal point of the Convention. He and the President will speak to tens of thousands of people at the stadium. He'll build toward the President's speech by giving unique insights and perspective of the President's governing character and the challenges/decisions over the last four years in a way that only he can. This is a standalone speech, not an intro."
