Luis Alvarez says he is still fighting.

WASHINGTON -- A 9/11 first responder with liver cancer, who testified last week before a U.S. House of Representatives subcommittee, has entered hospice care, according to multiple reports.

The New York Post says former NYPD detective Luis Alvarez, who responded to Ground Zero, confirmed the heartbreaking news on Facebook, saying there was "nothing else the doctors can do to fight the cancer.”

Alvarez and comedian Jon Stewart made headlines for their emotional pleas for lawmakers to support the 9/11 Victim Compensation Fund. Alvarez showed up to testify before a nearly empty panel despite having chemotherapy the next day. His cancer has been linked to the work he did after the 2001 terror attacks.

Fox News reports Alvarez said he was "still fighting" on Wednesday.

After Alvarez and Stewart's testimony, the House Judiciary Committee voted to permanently reauthorize the victims' fund. It now goes to the full House for a vote. If it clears the House, it would head to the Senate for consideration. It's unclear if it will be brought up for a vote on the Senate floor. According to CBS News, Sen. Mitch McConnell said he "will look at it."
