PHOENIX -- Gov. Jan Brewer on Friday signed a follow-on bill approved by Arizona legislators that make revisions to the state's sweeping law against illegal immigration -- changes she says should quell concerns that the measure will lead to racial profiling.

The law requires local and state law enforcement to question people about their immigration status if there's reason to suspect they're in the country illegally, and makes it a state crime to be in the United States illegally.

The follow-on bill signed by Brewer makes a number of changes that she said should lay to rest concerns of opponents.

"These new statements make it crystal clear and undeniable that racial profiling is illegal, and will not be tolerated in Arizona," she said in a statement.

But one of the changes -- which had been adopted by state lawmakers Thursday night -- says police could stop suspected illegal immigrants only while enforcing some other law or ordinance.
