PHOENIX (AP) - A federal judge will hear arguments today on whether Arizona's new immigration law should take effect July 29.
It will mark the first major hearing in one of the seven challenges to the strict law.
U.S. District Judge Susan Bolton also will consider arguments over Gov. Jan Brewer's request to dismiss the challenge filed by a Phoenix police officer and a nonprofit group.
The judge said last week that she wasn't making any promises on whether she'll rule on the officer's request to block enforcement of the law before it takes effect.
The law requires police, while enforcing other laws, to question a person's immigration status if officers have a reasonable suspicion that the person is in the country illegally.
