Hundreds of 9/11 first responders and local officials were in Washington, D.C. Wednesday to fight for an extension of the Zadroga Act.

They urged Congress to extend health care benefits for all first responders affected by cancer and other chronic diseases from exposure at Ground Zero.

Officials say more than 33,000 people are living with injuries and illnesses caused by the attacks.

The Zadroga Act is a $1.6 billion health and monitoring effort that has enrolled 72,000 first responders. The act will expire in October if not extended. The act's $2.75 billion victims' compensation fund will end in October 2016 if not renewed.

The bill has over 150 co-sponsors in the House. The Senate version has 37 co-sponsors.
