A former aide to Rudy Giuliani is out of prison and attacking the ex-mayor's ethics, saying he was ordered to help Giuliani's then-girlfriend get a below-market rent apartment.

Russell Harding, who got five years for embezzling more than $400,000 in city funds and downloading child pornography onto his computer, claims on his Web site that Giuliani's two terms as mayor were marked by ethical breaches.

Harding, 43, claims that in 1999, while he was the head of the city's Housing Development Corp., he was instructed to help Judith Nathan get a Manhattan apartment that would normally cost more than $3,000 for about half that price.

Nathan later married Giuliani. Her spokesman, Bob Leonard, denied Harding's allegations, saying she paid market rent for the apartment.
