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 the most controversial parts of the law on hold, hundreds of e-mails and phone calls - including some threats - have poured into the courthouse.

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.

1 overall draft pick Sam Bradford agreed to a six-year, $78 million contract with the St. Louis Rams on Friday night, with $50 million in guaranteed money.

The Rams and the former Oklahoma quarterback concluded negotiations in time for the first full-squad workout set for Saturday.

Bradford is the centerpiece of a rebuilding effort for the Rams, who were 1-15 last year in the first season under coach Steve Spagnuolo and are 6-42 the last three seasons.
