Elizabeth (Leo McGarry's sister — referenced)

Elizabeth exists offstage as Leo McGarry’s sister, a private family presence invoked through small, domestic tokens rather than direct action. Referenced on gift tags in Leo’s office, she functions as a humanizing anchor to Leo’s personal life, signaling the obligations and boundaries that complicate senior staff decisions. Though never present, her implied relationship shapes emotional stakes in moments of moral conflict and reinforces the administration’s private dimensions, providing staff a reminder of the personal costs that underlie public service.
