Casino Jack, starring Kevin Spacey, is in limited release right now if you're interested in the machinations of D.C. politics. Part straightforward re-telling of past events, and part fiction based on said events, the two often mix so it's hard to tell what is real and what is a story device. A bit confusing but worthwhile.
Take this short fantasy scene where the real Senator John McCain asks Abramoff a question in a Senate hearing. Abramoff daydreams what he'd really like to say to McCain, and others situated in the room who've benefited by his actions but are now there condemning him, instead of invoking his Fifth Amendment rights as he knows he must.
