title: Hurricane Katrina
text: In accordance with federal law , President George W. Bush directed the Secretary of the Department of Homeland Security , Michael Chertoff , to coordinate the Federal response . Chertoff designated Michael D. Brown , head of the Federal Emergency Management Agency , as the Principal Federal Official to lead the deployment and coordination of all federal response resources and forces in the Gulf Coast region . However , the President and Secretary Chertoff initially came under harsh criticism for what some perceived as a lack of planning and coordination . Brown claimed that Governor Blanco resisted their efforts and was unhelpful . Governor Blanco and her staff disputed this . Eight days later , Brown was recalled to Washington and Coast Guard Vice Admiral Thad W. Allen replaced him as chief of hurricane relief operations . Three days after the recall , Michael D. Brown resigned as director of FEMA in spite of having received recent praise from President Bush .
