Authors of the Zadroga health care bill are pushing to quickly expand coverage for 9/11 first responders.
Representatives Carolyn Maloney, Jerrold Nadler, and Peter King sent a letter to Health and Human Services Secretary Kathleen Sebelius.
They want her to appoint members to a panel created under the bill before the 10th anniversary of the attacks.
The panel would then review evidence and make suggestions on providing coverage for additional 9/11-related health conditions.
Last month, the doctor overseeing the program said studies did not show a clear link between cancer and dust at the World Trade Center.
First responders with cancer cannot currently benefit from the bill, but lawmakers hope new research will soon change that.
