Mexican President Visits Washington, Fuels Immigration Debate

May 19, 2010— -- President Barack Obama is honoring Mexican President Felipe Calderon and his wife with a state dinner at the White House tonight, but both leaders may hope to avoid an uncomfortable topic at the dinner table -- the issue of immigration.

At a stage-managed photo op with the Mexican first lady and some Maryland second-graders today, Michelle Obama found herself facing some tough prodding from one young girl, apparently the daughter of an illegal immigrant, who expressed her mother's fears.

"She says that, um, Barack Obama is taking everybody away that doesn't has [sic] papers," said the girl.

"Yeah, well, that's something we have to work on, right?" Michelle Obama responded. "Make sure that people can be here with the right kind of papers, right?"

"My mom doesn't have papers," said the girl.

President Calderon also took the unusual step of criticizing Arizona's new immigration law while at the White House, charging it will lead to discrimination.

President Obama agreed with that assessment, saying, "I think the law has the potential of being applied in a discriminatory fashion."

So as the immigration debate continues to pop up during the state visit, we want you to weigh in. Give us your thoughts in the comments below.
