The House Katrina Committee released an addendum to their February report today, as well as an accompanying document dump. There are seven PDF documents which were put up at this link today on the website of the House Government Reform Committee (also chaired by Rep. Tom Davis). The PDF files are very messy and confusing, consisting of a randomly organized scan of relevant documents, but the key point is summarized concisely in this story today from the Washington Post:
Michael D. Brown, former head of the Federal Emergency Management Agency, deliberately ignored a new national disaster plan and circumvented his boss, Homeland Security Secretary Michael Chertoff, in trying to manage the federal response to Hurricane Katrina directly with the White House, according to a new House report.
By disregarding the National Response Plan, finished in 2004, Brown deprived “the nation of an opportunity to determine whether the NRP worked,” the House investigation concludes in an addendum to its Feb. 15 report, “A Failure of Initiative,” scheduled for release today.
