"The federal official with the power to mobilize a massive federal response to Hurricane Katrina was Homeland Security Secretary Michael Chertoff...

Even before the storm struck the Gulf Coast, Chertoff could have ordered federal agencies into action without any request from state or local officials."

"White House and homeland security officials wouldn't explain why Chertoff waited some 36 hours to declare Katrina an incident of national significance and why he didn't immediately begin to direct the federal response from the moment on Aug. 27 when the National Hurricane Center predicted that Katrina would strike the Gulf Coast with catastrophic force in 48 hours. Nor would they explain why Bush felt the need to appoint a separate task force.

Chertoff's hesitation and Bush's creation of a task force both appear to contradict the National Response Plan and previous presidential directives that specify what the secretary of homeland security is assigned to do without further presidential orders. The goal of the National Response Plan is to provide a streamlined framework for swiftly delivering federal assistance when a disaster - caused by terrorists or Mother Nature - is too big for local officials to handle."
