President Bush is heading back to Washington after making a second tour of areas ravaged by Hurricane Katrina -- as New Orleans officials told any remaining survivors to leave the city immediately.
Mr. Bush made stops in Louisiana and Mississippi amid widespread criticism of the federal government's slow response to the disaster. New Orleans Deputy Police Chief Warren Riley says the city is completely destroyed and that there is no reason for anyone to remain there.
Rescuers are searching house to house for any survivors as efforts are made to collect bodies that litter the entire city. Officials also closed the breach in one of city's levees and have begun pumping out water. And residents of a New Orleans suburb were briefly allowed to check the condition of their homes and retrieve whatever they could.
Meanwhile, governors, emergency officials and volunteers are rushing to feed, clothe and shelter more than half-a-million people evacuated from the devastated Gulf Coast region. The U.S. government has sent more than 50,000 active duty and reserve troops to the region to help.
