A former New York policeman died Tuesday night as his 21-year-old son prepared to appear at the State of the Union address to symbolize the desperate health problems of some Sept. 11 workers.
Cesar Borja, 52, had been in intensive care, breathing through a tube, at Mount Sinai Medical Center, awaiting a lung transplant.
His son, college student Ceasar Borja Jr., was invited by Sen. Hillary Rodham Clinton, D-N.Y., to attend President Bush’s speech as a reminder of workers who were stricken with a host of illnesses after exposure to toxic World Trade Center debris.
The younger Borja learned of his father’s death in a phone call while eating dinner around 6:30 p.m. EST. He still planned to attend the speech, which was scheduled to begin 2 1/2 hours later.
