On Thursday night, Jon Stewart crashed Stephen Colbert's Late Show monologue, meaning he must miss TV almost as much as TV misses him. The reason for his visit? He's supporting a vital piece of legislation that Congress has been too petty to pass. The Zadroga Act, which provides healthcare to 9/11 first responders, is up for renewal. "The media won't pay attention to anything unless you are Donald Trump," Colbert quips and convinces Stewart to Trump it up in order to get people to pay attention to his cause.
