The truth about President Bartlet's MIA daughter is right here: She looks like former X-Files star Annabeth Gish. The West Wing has tapped Gish for the recurring role of Bartlet's never-before-seen eldest daughter, according to The Hollywood Reporter. The actress will make her debut in this season's first two episodes, which were written by exec producer (and successor to Aaron Sorkin's throne) John Wells. Sources say Gish is one of several new faces Wells plans to introduce on West Wing this season.
