Water crisis is "absolutely tragic," FEMA head says

The water crisis in Jackson, Mississippi, hit its fourth day on Thursday, as authorities are still struggling to get the city's water treatment plant back online and deliver safe drinking water to residents. In an interview with "CBS Evening News" anchor and managing editor Norah O'Donnell, FEMA administrator Deanne Criswell said her agency is responding immediately to help alleviate the "tragic situation."
