Meanwhile, a forthcoming Republican-authored congressional report lays considerable blame for the government’s slow response to Hurricane Katrina from President Bush down. The report, disclosed in Sunday’s Washington Post, singles out Homeland Security Secretary Michael Chertoff for being detached from events on the ground and responding: “late, ineffectively or not at all.” The report concludes: “Blinding lack of situational awareness and disjointed decision making needlessly compounded and prolonged Katrina’s horror.’’ The 600-page report will be released Wednesday.
