Arizona Attorney General Terry Goddard said Thursday he supports changes to federal immigration polices on local police raids.

The changes could impact Maricopa County Sheriff Joe Arpaio’s enforcement efforts, including raids on drop houses and businesses, conducted under a federal pact signed in April 2007.

Arpaio said, however, he will continue to conduct raids and crime sweeps under state immigration laws aimed at businesses that hire undocumented workers and the smuggling of illegal immigrants into the U.S.
