The state dinner Wednesday night for Mexico's President Calderon went as scripted, but the visit was dominated by the thorny issue that has raised heated debate in recent months -- immigration. Even Michelle Obama was pulled into the controversy during a visit with the Mexican president's wife to a local elementary school. Arizona immigration law dominates discussions with Mexican president.
President Calderon called the new immigration law in Arizona discriminatory.
"If we are divided, we cannot overcome these problems," Calderon said at the arrival ceremony Wednesday morning.
