The Obama administration and the Chamber of Commerce are two organizations you'd hardly expect to be in agreement with each other, but when it comes to immigration, they couldn't agree more:

The [Chamber of Commerce] has teamed up against the Legal Arizona Workers Act with allies including the American Civil Liberties Union, the Service Employees International Union and a Latino group that Justice Sonia Sotomayor once helped lead. The Obama administration is sending the government's top litigator to assist the chamber's lawyer.

This is a rare time when so-called compassionate immigration policy lines up with great economic sense.
