Homeland Security Secretary Michael Chertoff testifies about the Hurricane Katrina response during a hearing before the House Transportation and Infrastructure Committee on Capitol Hill in Washington February 16, 2006. Chertoff was questioned about his department's response to the disaster that hit the U.S. gulf coast last summer after former federal disaster chief Michael Brown told a Senate committee last week that homeland security was too preoccupied with a possible terrorist attack to deal with natural disasters.
