Earlier this month, Alvarez appeared in Washington with former Daily Show host Jon Stewart, to plead with Congress to extend the compensation fund for victims of the terrorist attacks and first responders. He entered hospice care days later.
We went to Ground Zero, the Pentagon and Shanksville to help people first and then help their families bury someone or something, a gaunt Alvarez told the House judiciary committee in a hearing which generated national attention.
You made me come down here the day before my 69th round of chemo and Im going to make sure that you never forget to take care of the 9/11 responders.
Alvarez was found to have colorectal cancer in 2016. He blamed his illness on three months spent in the rubble of the World Trade Center after the attacks in 2001.
