Republican presidential hopeful Rudy Giuliani has called a story raising questions about the accounting of his security expenses while he was mayor of New York a “hit job.”

Rudy Giulani denies any wrongdoing in the accounting of his security costs while he was New York City mayor.

Late Wednesday, Politico.com reported city records show Giuliani billed New York City government offices for at least $34,000 in security and travel costs on trips to the Hamptons in his last year in office, with charges spread around departments under his control.

“I thought the way the story was presented was like a hit job,” Giuliani said after the CNN/YouTube debate Wednesday night.

“Coming two hours before this debate, I kind of got the idea that it was not a legitimate story.”

“I would not accuse any of my opponents of doing it,” he said. “But who knows, it could be on the Democratic side.”
