A tough blow to Arizona's immigration law won't keep Prince William County Board Chair Corey Stewart from pushing for immigration reform in Virginia. A federal judge on Wednesday blocked key parts of the controversial crackdown in Arizona. Stewart says the judge's decision will make him push even harder, and he plans to unveil his "model legislation" this afternoon. Stewart grabbed national attention when he led the illegal immigration crackdown in Prince William County. The policy was later watered down to prevent claims of racial profiling.
