A proposed US law that would provide healthcare and compensation for those responders failed to pass in Congress this summer, causing anger amongst advocates who say the heroes of September 11 are being left behind.
On Thursday's Riz Khan we ask: What more should be done to help first responders of the 9/11 attacks?
Joining the programme are Richard Skinner of the FealGood Foundation, an advocacy group for 9/11 first responders, and Terry Miles, the executive director of the World Trade Center Environmental Health Center in New York.
This episode of Riz Khan aired from Thursday, September 9, 2010.
