First lady tells illegal immigrant's daughter that U.S. must 'fix' system

First lady Michelle Obama told the child of an apparent illegal immigrant on Wednesday that immigration policy should be "fixed" so her mother could remain in the United States.

During a trip to an elementary school in Silver Spring, Md., with the first lady of Mexico, Margarita Zavala, Obama took questions from one young girl who said that she had heard "that Barack Obama is taking everybody away that doesn't have papers," adding later that her mom lacks such paperwork.

"We have to work on that. We have to make sure that people can be here and get the right kind of papers; that’s exactly right," Obama responded. "We have to work on that. We have to fix that."

The exchange comes as Mexican President Felipe Calderon, who is visiting the United States today, is pressing President Barack Obama on a new Arizona immigration law that compels law enforcement authorities to confront individuals whom they suspect of being illegal immigrants to produce paperwork.

ABC News captured video of the exchange, seen below:
