President Bush issued an executive order Thursday allowing federal contractors rebuilding in the aftermath of Hurricane Katrina to pay below the prevailing wage. In a notice to Congress, Bush said the hurricane had caused "a national emergency" that permits him to take such action. Bush's action came as the federal government moved to provide billions of dollars in aid. The administration is using the devastation of Hurricane Katrina to cut the wages of people desperately trying to rebuild their lives and their communities.
