As Mayor, Rudy Giuliani insisted on locating the emergency control center in the World Trade Center, despite the fact that the WTC had already been the target of terrorist attacks. He wanted the poshly appointed center close to his office, it seems. For one thing, before he acknowledged his adultery during his second marriage, he used it for assignations with his then girlfriend, Judith Nathan.
Rudy Giuliani got into a little hot water by claiming that he spent more time at ground zero than the rescue and recovery workers. Sometimes a clarifying follow-up question can help clarify things. Perhaps he was including the (pre 9/11) time spent screwing his mistress there.
