The anti-Wall Street movement is expected to spread to Phoenix Saturday with a planned protest beginning in the downtown area.
Protest groups have been turning out to express their anger over costly health care, rising unemployment, corporate greed, and politicians who they believe fail to represent constituents.
Organizer Edward Medina tells ABC 15.Com that possibly as many as 5,000 or more people may show in the downtown area for the Occupy Phoenix movement.
At the other events, violence has broken out. Police clash with the protesters, and hundreds are being arrested.
Phoenix police Sgt. Steve Martos says they prepare for these kinds of events and would certainly be prepared for anything.
Organizers of Occupy Phoenix say they want to work with police to keep the event safe.
