PHOENIX – The fight over Arizona’s immigration law showed no signs of letting up Friday as the federal judge who blunted its force faced threats and the Republican governor who signed it considered changes to address any faults.

In the days since U.S. District Judge Susan Bolton put on hold the most controversial parts of the law, hundreds of e-mails and phone calls – including some threats – have poured into the courthouse.

About 70 people have been arrested in demonstrations protesting the law.

And a fund set up to help defend the new law added $75,000 Wednesday alone, giving the state more than $1.6 million to get Bolton’s ruling overturned.

Gov. Jan Brewer, who signed the law and appealed the ruling, has vowed not to back down, saying she’ll challenge Bolton’s decision all the way to the Supreme Court.

But Brewer said Friday she’d consider changes to “tweak” the law to respond to the parts Bolton faulted.

“Basically we believe (the law) is constitutional, but she obviously pointed out faults that can possibly be fixed, and that’s what we would do,” Brewer said. She said she’s talking to legislative leaders about the possibility of a special session but said no specific changes had been identified.

In her temporary injunction, Bolton delayed the most contentious provisions of the law, including a section that required officers to check a person’s immigration status while enforcing other laws. Bolton indicated the federal government’s case has a good chance at succeeding in its argument that federal immigration law trumps state law.

But she allowed police to enforce the law’s bans on blocking vehicle traffic when seeking or offering day-labor services and a revision to the smuggling ban that lets officers stop drivers if they suspect motorists have broken traffic laws.

Bolton also let officers enforce a new prohibition on driving or harboring illegal immigrants in furtherance of their illegal presence.

Democrats scoffed at Brewer’s desire to change the law, with a key House minority leader calling it laughable.

“Why would we help her?” asked Rep. Kyrsten Sinema of Phoenix.

“This bill is so flawed, and clearly a federal judge agrees,” Sinema said.

House Speaker Kirk Adams said there would be little support among fellow Republicans to weaken the law. Attorneys have begun reviewing the law to identify possible changes, he said: “It’s embryonic.”

Sen. Russell Pearce, the law’s chief sponsor, said he would only back changes to make it stronger.

Federal officials in charge of court security wouldn’t say whether anyone made a death threat against Bolton and wouldn’t provide specifics of the threats they were examining.
