"There's nothing new or insightful on these tapes," Knocke said. "We actively participated in the lessons-learned review and we continue to participate in the Senate's review and are working with them on their recommendation."

New Orleans Mayor Ray Nagin, a critic of the administration's Katrina response, had a different take after watching the footage Wednesday afternoon from an AP reporter's camera.

"I have kind a sinking feeling in my gut right now," Nagin said. "I was listening to what people were saying -- they didn't know, so therefore it was an issue of a learning curve. You know, from this tape it looks like everybody was fully aware."

Some of the footage and transcripts from briefings Aug. 25-31 conflicts with the defenses that federal, state and local officials have made in trying to deflect blame and minimize the political fallout from the failed Katrina response:

-- Homeland Security officials have said the "fog of war" blinded them early on to the magnitude of the disaster. But the video and transcripts show federal and local officials discussed threats clearly, reviewed long-made plans and understood Katrina would wreak devastation of historic proportions. "I'm sure it will be the top 10 or 15 when all is said and done," National Hurricane Center's Max Mayfield warned the day Katrina lashed the Gulf Coast.

"I don't buy the `fog of war' defense," Brown told the AP in an interview Wednesday. "It was a fog of bureaucracy."

-- Bush declared four days after the storm, "I don't think anybody anticipated the breach of the levees" that gushed deadly flood waters into New Orleans. He later clarified, saying officials believed, wrongly, after the storm passed that the levees had survived. But the transcripts and video show there was plenty of talk about that possibility even before the storm -- and Bush was worried too.

White House deputy chief of staff Joe Hagin, Louisiana Gov. Kathleen Blanco and Brown discussed fears of a levee breach the day the storm hit.

"I talked to the president twice today, once in Crawford and then again on Air Force One," Brown said. "He's obviously watching the television a lot, and he had some questions about the Dome, he's asking questions about reports of breaches."

-- Louisiana officials angrily blamed the federal government for not being prepared but the transcripts shows they were still praising FEMA as the storm roared toward the Gulf Coast and even two days afterward. "I think a lot of the planning FEMA has done with us the past year has really paid off," Col. Jeff Smith, Louisiana's emergency preparedness deputy director, said during the Aug. 28 briefing.
