Protesters Blast Ariz. Gov. At Boston Meeting

A coalition of immigrant groups bused in advocates from around the East Coast for a rally Saturday to protest Arizona's controversial immigration law, recently signed by Brewer.

Protesters in Copley Square said Brewer was a bigot and called for the end of what they said was "racist deportation." They later marched to a hotel where Brewer was attending the annual governors meeting.

The Arizona law, which is facing a U.S. Justice Department challenge, requires police to question people about their immigration status while enforcing other laws if there's reason to suspect someone is in the country illegally.

Brewer has said Arizona had to act because the federal government isn't doing enough border enforcement.
