Philadelphia Mayor Michael Nutter is the current president of the organization, whose summit will bring more than 30 mayors from across the U.S. to Philadelphia Thursday and Friday.
The group's summit will focus on how cities can utilize technology and innovation to create sustainable solutions to challenges, increase civic engagement and improve the quality of public services. It's being done in conjunction with Temple University's Fox School of Business.
Local municipal unions are planning protests outside the hotel where the group will be meeting. They're engaged in a long-running contract dispute with Nutter.
