Bush takes blame for flaws in Katrina response

The next part of the operation
Chertoff said the relief operation had entered a new phase.

Initially, he said, the most important priority was evacuating people, getting them to safety, providing food, water and medical care.

"And then ultimately at the end of the day, we have to reconstitute the communities that have been devastated," Chertoff added.

He said the federal government would look increasingly to state and local officials for guidance on rebuilding the devastated communities along the Gulf Coast.

"The federal government can't drive permanent solutions down the throats of state and local officials," Chertoff said. "I don't think anyone should envision a situation in which they're going to take a back seat. They're going to take a front seat," he said.

Properly divvying up public money
Chertoff said that teams of federal auditors were being dispatched to the stricken areas to make sure that billions of dollars worth of government contracts were being properly spent. "We want to get aid to people who need it quickly, but we also don't want to lose sight of the importance of preserving the integrity of the process and our responsibility as stewards of the public money," Chertoff said.

"We're going to cut through red tape," he said, "but we're not going to cut through laws and rules that govern ethics."

Meanwhile, Defense Secretary Donald H. Rumsfeld said that some military aircraft and other equipment may be able to move out of the Gulf Coast soon.

"We've got to the point where most if not all of the search and rescue is completed," said Rumsfeld, who is attending a NATO meeting in Berlin. "Some helicopters can undoubtedly be moved out over the period ahead."

He also said there is a very large surplus of hospital beds in the region, so those could also be decreased. The USS Comfort hospital ship arrived near the Mississippi coast late last week. Rumsfeld added that nothing will be moved out of the area without the authorization of the two states' governors, the military leaders there and the president.

148 injuries in the last two days
Elsewhere, workers with the Centers for Disease Control and Prevention aren't finding many sick people, even though the specter of diseases has alarmed relief and rescue figures. Instead, between 40 and 50 percent of patients seeking emergency care have injuries. The CDC has counted 148 injuries in just the last two days, Carol Rubin, an agency hurricane relief specialist, said by telephone from the government's new public health headquarters in New Orleans' Kindred Hospital.

While she couldn't provide a breakdown, Rubin said they saw injuries and carbon monoxide exposure from generators are among them. Those are particularly worrisome because they're likely to become more common as additional hurricane survivors re-enter the city in coming days, she said.

The message: Those injuries are preventable, if people take proper precautions, Rubin stressed.
