The House is expected to vote on new funding for the 9/11 Victim Compensation Fund on Friday.
NYC firefighter Kenny Specht spent two months at Ground Zero, and he says he got sick from his time working on the pile.
Specht says he has been fighting for first responders' health benefits and care since 2009, roughly around the time he was being treated for thyroid cancer.
Specht and other advocates say they've made many trips to Washington, fighting for compensation for the men and women who are now sick or will become sick.
The 9/11 Victim Compensation Fund is expected to cost American taxpayers $10.2 billion over the next decade.
The bill, which was originally called the Zadroga Act, has been renamed to honor NYPD Detective Luis Alvarez, who died last month of 9/11-related cancer, and city firefighter Ray Pfeifer, who died in 2017.
If the measure clears the House, it will then head to the Senate.
