VIDEO : Jon Stewart's Latest Viral Clip Reminds Fans Of 'Crossfire' Interview

(CNN)Having kept a relatively low profile since leaving "The Daily Show," Jon Stewart made headlines again this week, delivering an impassioned plea for 9/11 first responders during an emotional congressional hearing. It wasn't the first time that a Stewart clip in which he urged an institution to do better has gone viral. In fact, it was 15 years ago when he specifically took CNN and the wider media to task in an appearance on the debate show "Crossfire," which effectively served notice that despite the primary mandate to entertain, late-night comedians needn't shy away from more serious critiques and policy positions that propelled their monologues into the political conversation.
