Moore and a camera crew were seen in Covington, Louisiana, last Friday, the newspaper reported, but quoted a spokesman for the crew as saying: "We didn't go there to make a documentary. We're participating in the relief effort."
"There is much to be said and done about the manmade annihilation of New Orleans, caused NOT by a hurricane but by the very specific decisions made by the Bush administration in the past four and a half years," Moore wrote.
"Do not listen to anyone who says we can discuss all this later. No, we can't. Our country is in an immediate state of vulnerability.
"More hurricanes, wars, and other disasters are on the way, and a lazy bunch of self-satisfied lunatics are still running the show."
