Griffin was a Councilman who ran against Assistant D.A. Landon Walker. He won the election by a landslide after his opponent was framed to be the head of HR by Alonzo Quinn, Griffin's campaign manager and the actual head of HR.
Quinn's actions led to Maxine Angelis's designation as a POI and Christopher Zambrano's death. After Ed Griffin was elected mayor, Quinn became his Chief of Staff.
