Today the confirmation hearings for Supreme Court nominee Judge Sonia Sotomayor begin. To find out more about the nominee, we talk to Margarita Rosa, the Executive Director of Grand Street Settlement in New York who first met Sonia Sotomayor when they were undergrads at Princeton. We are also joined by Ellen Chapnick, Dean of the Social Justice Program at Columbia Law School and a Lecturer–in-Law. She co-taught a class with Sonia Sotomayor and has known her since the late 1990’s.
