The federal government remains partially shut down, but the U.S. Supreme Court's nine justices are back at work. Today is the first day of their new term.

Another is the first major campaign finance case since Citizens United in 2010. Once again the outcome of a number of cases could depend on Justice Kennedy. Last year his vote tipped more five-to-four decisions than any other justice. Diane and her guests talk about some of the key issues before the nation's highest court this fall.
