OBAMA SAYS BILL IS 'MISGUIDED'
President Barack Obama gave a speech earlier this morning at an active duty naturalization ceremony at the White House, calling for the government to enact immigration reform nationally, or the door will be left open to "irresponsibility by others."
"Indeed, our failure to act responsibly at the federal level will only open the door to irresponsibility by others," Obama said "And that includes, for example, the recent efforts in Arizona, which threatened to undermine basic notions of fairness that we cherish as Americans, as well as the trust between police and their communities that is so crucial to keeping us safe."

U.S. Democratic Rep. Raúl Grijalva closed his Tucson and Yuma offices at noon because of multiple death and violence threats after he called for a statewide boycott of conventions to pressure Brewer into a veto, according to the Arizona Daily Star.
