COLBERT: Somebody else has a book right now. Hillary Clinton does. And that book is called “What Happened.” And, uh, she remembers you from the campaign in the book. I don't know if you're aware of this, but I'd like your reaction to this: Hillary Clinton says that your attacks during the campaign caused lasting damage, making it harder to unify progressives. What is your response to that accusation — that you damaged America by damaging Hillary Clinton?

SANDERS: Actually, the case is that the progressive movement today and grass-roots activism is stronger than it has been in many, many years. As a result of our campaign, millions of young people began to vote for the first time, became engaged in the political process. We're seeing young people all over this country, working-class people, running for office, from school board to Congress. So, I think there is a level of understanding now among people — and what [my] book is about — that we have got to stand together against Trump's efforts to divide us up, take on the billionaire class and make that political revolution, so that we have a government that works for all of us, not just the 1 percent.
