This week the high court is on its winter break, but the team here at Amicus wanted to talk about DACA, the travel ban, and issues around immigrants, refugees, and the law. We talk Americanism. Who is American and how? What do the courts have to say about who can be here and who cannot? What role do the courts play in figuring out who belongs here and who doesn’t? To tackle these thorny and sometimes super-wonky questions, Dahlia Lithwick is joined by Stephen Vladeck who teaches law at the University of Texas. Vladeck’s teaching and research focus on federal jurisdiction, constitutional law, and national security law. He’s CNN's Supreme Court analyst, co-editor in-chief of the Just Security blog, and a senior contributor to the Lawfare blog.
