In character as Secretary of State Elizabeth McCord, the lead character in the CBS drama "Madam Secretary," Tea Leoni was delivering an urgent address about the need for the United Nations to fight Hizb al-Shahid, a fictional terrorist group reminiscent of Islamic State, for an episode airing Sunday.

Washington, DC is excited for the series premiere of Madam Secretary. Madam Secretary stars Téa Leoni as Elizabeth McCord, the shrewd, determined, newly appointed Secretary of State who drives international diplomacy, battles office politics and circumvents protocol as she negotiates global and domestic issues, both at the White House and at home.
