Michael D. Brown said that he could not recall if he personally called the homeland security secretary, Michael Chertoff, to relay the account of the levee breach. Two senior Homeland Security Department officials, who testified after Mr. Brown, said that his unwillingness to honor the chain of command and give regular updates to Mr. Chertoff or others in the department severely hampered the department's response.
