On Tonight's CBS Evening News

In an exclusive interview with Katie Couric, Rudy Giuliani responds to the Politico's report.

Joe Lhota, an ex-mayoral aide, previews Giuliani's defense in a statement his campaign just released to reporters:

“To ensure the safety of the Mayor of the City of New York and his family, the NYPD assigned security to them on a 24/7/365 basis. The cost of this security was paid by the NYPD budget. Dating back as far as the Mayor’s first term in office, the practice was that when security-related expenses were incurred, they were paid for with an Office of the Mayor credit card. The practice was put into place to ensure timely payment and the monthly credit card bill was paid promptly from the Mayor’s Office budget. Such costs were allocated throughout the various divisions within Mayor’s office. Sometime there after, but before the end of each fiscal year, the NYPD would reimburse the Office of the Mayor for such expenditures and therefore these divisions were never deprived of any monies.”
