In an interview for upcoming film The Campaign, the actor talks about being exposed to politics from a young age, including through his uncle Nick Galifianakis (a North Carolina senator from 1967 to 1973). He also talks about the influence of the Koch brothers on the characters played by Aykroyd and Lithgow:
I think it is pretty obvious that the Motch brothers represent the Koch brothers. I disagree with everything they do. They are creepy and there is no way around that. It’s not freedom what they are doing.
