This Powerful Image Shows Why Jon Stewart Is Fighting So Hard For 9/11 Heroes

The Daily Show shared a powerful image from Jon Stewart's return earlier this week that shows just how vital programs offering aid to 9/11 emergency workers really are.

Stewart went back to his old stomping grounds to lobby for Congress to reauthorize the James Zadroga 9/11 Health and Compensation Act , which helps cover medical expenses for first responders now suffering from health problems likely caused by toxic substances in the air around Ground Zero in the days after the 9/11 attacks. He brought with him retired FDNY firefighter Kenny Specht, who first appeared on the show years ago as part of a panel of 9/11 first responders fighting for Congress to provide aid.

But three of the panelists who appeared with Specht on that first show didn't join Stewart Monday night.

"Five and a half years ago we did a show, 75 percent of the panel's no longer here," Specht said, noting two of the panelists are ill and one has passed away since the 2010 appearance.
