A state of disaster is being declared in seven Illinois counties devastated by a wave of tornadoes on Sunday. Governor Pat Quinn issued the declaration as the death toll continued to climb across his state. At least five people have been killed and more than three dozen others injured. Tens of thousands of people are without power. A full house at Soldier Field had to evacuate for a time as the storm system approached Sunday afternoon. They were later allowed back to their seats. Hundreds of flights were affected heading into and out of the region.
