FSince the death of the First Lady, Kirkman has been ineffective, actually vindictive. In this episode we see hm do several things that would go against the guy who wanted everyone treated equally. Apparently, he is missing obligatory trips, not reading his briefings, and failing to sign legislation. His daughter is getting into trouble at her school. He isn't seeing the forest for the trees because of his intense anger.
