Dozens of 9/11 recovery workers are demanding that Congress renew programs offering money and heath care to people exposed to toxic dust after the terror attacks.

The former ground zero workers and survivors were joined at the World Trade Center site on Thursday by members of New York's congressional delegation.

Congress authorized billions of dollars in payments and health services for people with illnesses potentially linked to dust released when the twin towers collapsed after they were struck by hijacked planes in 2001.

But those programs are set to expire next year.

Advocates for the sick say the health programs are essential for people with complicated, often incurable illnesses.

Congress initially limited the programs because of cost concerns.
