Arizona suburb sues Scottsdale for cutting off its water

Arizona's drought conditions have reached a critical stage for one community just outside Scottsdale. Residents in the unincorporated community of Rio Verde Foothills are suing the city to restore water delivery services, cut off due to extreme drought conditions in the Colorado River. That's where the majority of Scottsdale's water comes from. Chief Climate Correspondent Bill Weir joins "CNN This Morning" to discuss.
