Philadelphia Mayor Michael Nutter is set to take the podium Thursday night at the Democratic National Convention.
Nutter was scheduled to speak Wednesday, but organizers made a late schedule change and moved his speech to Thursday instead.
The Philadelphia mayor not only represents the city, but is also the president of the U.S. Conference of Mayors.
Former president Bill Clinton is scheduled to speak to delegates Wednesday night. Delaware Gov. Jack Markell is also scheduled to address the DNC Wednesday night.
President Obama will address delegates Thursday night.
