WASHINGTON (AP) -- A Senate inquiry into the government's Hurricane Katrina failures ripped the Bush administration anew Thursday and urged the scrapping of the nation's disaster response agency. But with a new hurricane season just weeks away, senators conceded that few if any of their proposals could become reality in time. The bipartisan investigation into one of the worst natural disasters in the nation's history singled out President Bush and the White House as appearing indifferent to the devastation until two days after the storm hit.
