Picayune reported Friday. Officials said there were fewer fires than in recent days, with 11 Thursday, the paper said. Bush administration officials were busy rushing fresh aid to the region while also trying to blunt the political fallout over the federal response to what, at an estimated $100 billion to $200 billion, could be the costliest natural disaster in U.S. history. A Pew Research Center poll found 67 percent of Americans thought Bush could have done more to speed up relief efforts, and just 28 percent believed he did all he could. The president's approval rating fell to 40 percent, down four points since July to the lowest point Pew has recorded. --SP 2113 Local Time 1813 GMT
