Mexican President Likely to Give President Obama an Earful About Arizona Immigration Law

William Booth of the Washington Post reports that "President Felipe Calderón arrives in Washington this week for a two-day state visit that was supposed to be a celebration of U.S.-Mexican cooperation in his drug war. Instead, it is likely to showcase Mexico's frustration over Arizona's tough new immigration law, which Calderón has described as anti-Mexican."

President Calderon's protest of the Arizona immigration law demonstrates why the federal government has traditionally exercised exclusive authority over immigration -- because state involvement may affect the nation's foreign relations with other countries.  Mexio's prot4ests likely will be relevant to many of teh lawsuits challenging the Arizona law.
