This afternoon, The Nation’s Ari Berman and Ari Melber appeared on MSNBC’s Now with Alex Wagner to discuss Arizona’s controversial immigration law, which the Supreme Court will consider later this week. “It’s a very big deal because the federal government has jurisdiction over foreign policy, which includes immigration policy,” said Berman. “If the Supreme court favors Arizona, which I think there’s a very good chance they will, it’s going to open the door to a lot of other states passing these kind of laws.”
