Protesters march near City Hall during a May Day immigration rally in Los Angeles, California in this May 1, 2010 file photo. Arizona Corporation Commissioner Gary Pierce has dared Los Angeles officials to turn off the electricity they get from Arizona if they are serious about boycotting the state over its crackdown on illegal immigration. In a sharply worded letter to Mayor Antonio Villaraigosa, Pierce noted that Los Angeles gets 25 percent of its electricity from Arizona and challenged the mayor to cut off that supply.
