Jon Stewart visited Fox News for the first time in four years to help 9/11 victims

In the heyday of "The Daily Show," Jon Stewart and Fox News were mortal enemies. In fact, in 2015 he called the channel “a whale of a network - in that we’ve been chasing you our whole lives and just can’t kill you.” So this afternoon, viewers might have been surprised to see the comedian pleasantly chatting with Fox News anchor Shepard Smith. It was Stewart’s first visit to the network since 2014, when he appeared on the now-defunct "O’Reilly Factor." Smith started off by poking fun at Stewart’s combative past with Fox News, asking him, “Why are you here?” But Stewart was visiting Fox News for a more serious reason. He’s been a vocal supporter of 9/11 victims and is pushing for Congress to renew the Victims Compensation Fund in 2020. If they don’t, says John Feal, a 9/11 first responder who also appeared on Fox News with Stewart, there would be life-threatening consequences for 9/11 survivors that are sick from breathing in toxic fumes. While some people outside of New York may feel somewhat disconnected from the events of 9/11, it’s still a day-to-day tragedy for victims. “For them it’s never ended,” Stewart said. “For first responders, for veterans, for trade unions that were down there, for survivors, for volunteers, there’s still a ticking time-bomb inside them.”
