Hutchison (off‑stage Nightline leak source)

Hutchison functions as an off‑stage information conduit whose unauthorized disclosure on item A3‑C3 directly destabilizes White House communications. Named by Leo McGarry as responsible for the Nightline leak, Hutchison occupies a narrative role that channels external media pressure into the West Wing, forcing senior staff to confront loss of control and to triage reputational damage around the Josh Lyman controversy. The character remains absent on‑screen but exerts outsized influence: a terse, culpable presence that accelerates internal anxiety and operational scramble.
