Beginning 1999, Moss portrayed the recurring role of Zoey Bartlet in the White House television drama The West Wing, playing the daughter of Martin Sheen and Stockard Channing; she would portray the character until the series finale in 2006.[7] Moss's character became integral to the fourth season of the show; in a retrospective on the series, The Atlantic noted: "Aaron Sorkin made [Moss] the centerpiece of the explosive fourth-season finale where he basically engineered the most insane cliffhanger possible. It required Zoey to be a bit of a pain with her fancy French boyfriend, but Moss always made her relatable, even when the plot required otherwise."[9]
