I had heard of long-time Georgia congressman John Lewis and his role in the civil rights movement but had never actually seen him. I found this interview with Stephen Colbert quite moving.
What I found particularly refreshing was that he seems to reject the parochialism so common among US politicians that views policies only in terms of what is good for America (especially the top 1%), Instead he emphasizes the idea that we need to look at what is good for the world as a whole.
