Federal Emergency Management Agency, sought the approval from Homeland Security Secretary Mike Chertoff roughly five hours after Katrina made landfall on Aug. 29. Brown said that among duties of these employees was to "convey a positive image" about the government's response for victims.
Before then, FEMA had positioned smaller rescue and communications teams across the Gulf Coast. But officials acknowledged Tuesday the first department-wide appeal for help came only as the storm raged.
Brown's memo to Chertoff described Katrina as "this near catastrophic event" but otherwise lacked any urgent language. The memo politely ended, "Thank you for your consideration in helping us to meet our responsibilities."
