Jon Stewart's 2004 appearance on Crossfire

On October 15, 2004, American comedian Jon Stewart appeared on CNN's Crossfire, hosted by media commentators Tucker Carlson and Paul Begala. The Daily Show, a satirical talk show hosted by Stewart, had released America (The Book): A Citizen's Guide to Democracy Inaction earlier that year; in theory, Stewart's appearance on Crossfire, a show that featured debate between left- and right-wing personalities, was intended to boost sales of the book.
