MEXICO CITY -- Mexican President Felipe Calderón condemned the new Arizona law, saying it “opens the door to intolerance, hate, discrimination, and abuse in law enforcement,” El Universal reports. Calderón said no one should stand idly by as the rights of Mexican citizens are under attack. He promised to help Mexican citizens -– whether they have papers or not -– address any rights violations. The Mexican president welcomed President Obama's rejection of the Arizona law, but affirmed that the new law -- which he called “opportunistic legislation" driven by election politics -- "affects the bonds of friendship, commerce, tourism and culture with Arizona.”
