He's an elitist, anti-gun British snot. The only reason he continues to harp on the 2A is because those shows he did immediately after Newtown generated the highest ratings he's ever had.
He and CNN think if they keep doing it they can hit those numbers again. Fortunately, his ratings are back to what they were before Newtown (practically non-existent), however they keep beating that horse, because they can't think of anything else to raise his ratings, because no one wants to hear the drivel of an elitist, anti-gun British snot. That and no one watches CNN anymore, and he'll be off within a year maybe two, as they go in search of someone, anyone to bring them ratings.
