Hurricane Katrina Marks 10th Anniversary

This week marks the 10th anniversary of the most expensive and destructive natural disaster in U.S. history -- Hurricane Katrina.

President Obama was in New Orleans on Thursday to tour some of the affected areas, and to celebrate the remarkable revival and talk about ongoing recovery efforts.

Former President George W. Bush and his wife, Laura, will visit New Orleans today, and former President Bill Clinton will visit on Saturday to speak at the city's official commemoration event.

More than 18-hundred lives were lost as a result of Hurricane Katrina, and exceeded more than $145-billion in costs for insured and uninsured residents.
