"In the evolution of the stories, politics and campaigning has been the arena least explored. We're trying to rectify that balance.""It's a slightly unreal element on the show that we haven't had the political sharks circling the White House. That dynamic will now be added." - Lawrence O'Donnell, Jr.

I had a similar scene a couple of years later in the episode in which my brother had committed suicide and I had the scene where I break down. I remember the way it unfolded I couldn't control myself, I couldn't stop, I was so vulnerable. I went right back at her and I said 'you know what, you once said you couldn't do this particular scene [without me] well there is no one on this earth I could have done this with, except you. So that's memorable for me. - Richard Schiff
