Mexican President Felipe Calderon took the unusual step Wednesday morning of criticizing an American law while visiting the White House, saying cooperation is needed to fix the US-Mexican immigration issue but “such laws as the Arizona law that is forcing our people to face discrimination. If we are divided, we cannot overcome these problems.”…

President Obama did not specifically mention his opposition to the Arizona law, though White House officials say it will be a topic of discussion during the two leaders closed-door meetings throughout the day at the White House.

“Mexican-American families have been here for centuries,” President Obama said, noting “our proud tradition as a nation of immigrants, all of whom strengthen our American family and who join us today. Working together, we have built upon these bridges. We’ve forged a new era of cooperation and partnership between our countries based on mutual interest, mutual respect and mutual responsibility.”
