The museum planned for the site of the Sept. 11, 2001, attacks in New York should include a memorial to workers who died after becoming ill during recovery and cleanup, two state lawmakers said Sunday.

Assemblyman Michael Gianaris and Senator Martin Golden said they would introduce legislation to ensure those workers are recognized.

"We want to tell the story of the 9/11 workers who rushed here to help put the city back on its feet, who got sick because they did that, and now unfortunately many of them have died," Gianaris said at a news conference attended by ailing first responders and family members.

The administration of U.S. President George W. Bush, along with state and local governments, have been criticized for being slow to acknowledge that many people developed debilitating illnesses from exposure to toxic materials at the World Trade Center site.

The event came a day after the funeral of police officer Cesar Borja, 58, a Filipino immigrant who died of lung disease believed to have resulted from recovery work.

A message to a spokeswoman for the World Trade Center Memorial Foundation, which is building the memorial and museum, was not immediately returned Sunday.
