‘Madam Secretary’ Star Jill Hennessy on TV, Politics and Her Music
Jill Hennessy got her start in television as Assistant District Attorney Claire Kincaid on the NBC hit "Law & Order," holding her own opposite the great Sam Waterston. She went on to headline "Crossing Jordan" for the network, and most recently kicked off a recurring role on CBS's "Madam Secretary," as a "defense intelligence agency handler." All the while, Hennessy has kept up a double life as a rock 'n' roller, releasing her second album, "I Do," just last week. John Heilemann sat down Hennessy to talk about her career playing political roles and how she balances it with her musical ambitions.
