Shortly after the Obama administration announced its federal lawsuit challenging Arizona's new immigration law , Boulder's city council backed away from its resolution denouncing the measure in favor of a more general statement that calls for the reform of national immigration laws. Several council members say they might have acted too harshly on May 5 in officially criticizing the Arizona law, which grants law enforcement there the authority to check the documentation of anyone they suspect is in the country illegally. According to the Daily Camera , Boulder's resolution would have included the ban of nonessential employee travel to the state. Jody Jacobson, a spokeswoman for the city, says city offices have received a flood of calls and e-mails from around the country---mostly angry about Boulder's stand on Arizona's law. An official statement is expected to be posted on bouldercolorado.gov  explaining the council's revised position. Meanwhile, Arizona Governor Jan Brewer has canceled an annual conference of U.S. and Mexican politicos who govern along the southern border after all six Mexican governors said they would not attend the gathering, which was slated to take place this year in Arizona. The six say the law Brewer signed in April is "based on ethnic and cultural prejudice contrary to fundamental rights" (via The New York Times ).
