In Mexico, President Felipe Calderón has joined the voices of opposition to a new law in Arizona that forces police officers to determine the immigration status of someone they suspect of being an undocumented immigrant. Republican Governor Jan Brewer signed the bill on Friday following its approval in the state legislature earlier in the week. Opponents call it the harshest anti-immigrant measure in the country and a license for racial profiling. On Monday, Calderón said the measure will breed "racial discrimination."

Mexican President Felipe Calderón: "A legislation, which opens the door to unacceptable racial discrimination, is set in motion. Mexico’s government will use everything in its power to defend the rights of Mexicans who are affected by this legislation, and we’ll spare no effort to ensure the dignity of every fellow compatriot."

The law’s passage has spurred calls for a boycott of Arizona’s economy.
