From Today's New York Times:
"On at least three occasions, in responding to accusations that the
city failed to adequately protect the health of workers in the
wreckage, (Giuliani) has boasted that he faced comparable risks himself. In one
appearance he declared that he had been in the ruins “as often, if not
more” than the cleanup workers who logged hundreds of hours in the
smoldering pile.
Another time he brushed aside safety claims by
asserting that his long hours at the site had left him susceptible to
“every health consequence that people have suffered.”
So, how much time did Mayor Giuliani spend at ground zero?
A complete record of Mr. Giuliani’s exposure to the site is not
available for the chaotic six days after the attack, when he was a
frequent visitor. But an exhaustively detailed account from his mayoral
archive, revised after the events to account for last-minute changes on
scheduled stops, does exist for the period of Sept. 17 to Dec. 16,
2001. It shows he was there for a total of 29 hours in those three
months, often for short periods or to visit locations adjacent to the
rubble. In that same period, many rescue and recovery workers put in
daily 12-hour shifts.
