Five-time Oscar nominee Glenn Close will guest-star on NBC's The West Wing later this month playing a potential Supreme Court justice. "A conservative judge just died, so it's the business of trying to get her nominated and the confirmation drama around it," costar John Spencer explains to TV Guide Online. "The Senate we're dealing with is a Republican majority, as it is in the real world."

He showed a great deal of candor and passion for the show during his talk, and had a good feel for (and devotion to) the show's history; the writing staff is always on guard against repeating themselves (e.g. they wouldn't have done another Supreme Court arc this season without bringing new angles to the table)
