Deputy Whip (unnamed, appears via Donna to Josh in S1E16)

An unnamed congressional deputy whip who surfaces only through routed communications and brief mentions; they operate offstage as a node in the flow of Capitol Hill pressure that reaches senior White House staff. Their call arrives to Josh via Donna, instantly reframing personal moments into political priorities. The deputy whip functions as an institutional interlocutor whose authority and requests compel rapid tactical response, signaling broader legislative stakes without appearing on-screen or engaging directly in public-facing politics.
