The festive Christmas spirit at the annual White House tree-lighting celebration is dimmed when the President learns that Christian relief workers have been jailed in Islamic Northern Sudan. Bartlet welcomes his three independent daughters, Zoey (recurring guest star ELISABETH MOSS), Liz (recurring guest star ANNABETH GISH) and Ellie (recurring guest star NINA SIEMASZKO), and is surprised to learn that Liz's husband, Doug Westin (recurring guest star STEVEN ECKHOLDT), wants to vie for Congress in New Hampshire. Meanwhile, when the licenses of some doctors in Oregon are suspended after they administer drugs in an assisted suicide, Toby tries to keep the President from being bogged down in a debate--and clashes with Will, whom he sends to convince the Vice President to address the political juggernaut instead.
