Playing a TV character for seven years is almost like when you do a play. You live, breathe, and everything else with that character 24-7 for six months or four months or whatever, and that gets very deep in your blood. When you do a TV character for seven years, that's a long time. It becomes a seminal era in your life.

I turned down a lot of things - some very lucrative - because I could afford to at that time. That didn't lead to a happy place. I was happy to spend time with my family, get to know my daughter, who was born during The West Wing.

I still have the mentality of someone who doesn't know where he's going to sleep and doesn't know if he has enough money for gas to get to the next job interview. I don't think that mentality ever leaves, you know?

I have to admit I've rarely been happier in my life. I have been absolutely thrilled to be back in New York and living a block from where I grew up. Just to be back in New York and, quite honestly, away from Hollywood has been an absolute thrill for me. I feel like I'm a real actor again.

I would love to be in the position where the role is challenging enough that I need three months to prepare for it and then six months to live the life of character.

I imagine an America that can actually change. That we become a nation that prospers again but without pillaging the resources of nations that make their people hate us. That we become a nation that, as the constitution says in its preamble, its very first paragraph, 'promotes the general welfare' of its people.

I didn't expect NBC would be at all thrilled about me, because the year before the West Wing I had rejected a pilot at the last minute and got them very upset. I ended up not coming to the casting - in fact it happened four different times because I just wasn't convinced that I wanted to do television.
