11 Congressional Republicans (no Democrats) authored the Congressional Report on Katrina entitled "Failure of Initiative". Here are some of the highlights:

"Katrina was a national failure, an abdication of the most solemn obligation to provide for the common welfare" "Katrina was a failure of initiative" "Chertoff executed his responsibilities late, ineffectively, or not at all." "a litany of mistakes, misjudgments, lapses and absurdities all cascading together, hobbling any collective effort to respond." “We are left scratching our heads at the range of clumsiness and ineptitude that characterized government behavior before and after this storm,” "This crisis was not only predictable, it was predicted" "We had a tabletop exercise — Hurricane Pam — that predicted at a level 4 [hurricane], the dam was going to be breached." "If this is what happens when we have advance warning, we shudder to imagine the consequences when we do not," "Four-and-a-half years after 9/11, America is still not ready for prime time." "The White House was clearly in a fog" "Chertoff was clearly detached. He didn't even go to New Orleans 'til Wednesday; then you have [Michael Brown], who was clueless and negligent." "[The Department of Homeland Security] just stood and watched it fail"
