Backup tonight for Rudy Giuliani and his argument countering yesterday’s Politico story, which alleges that he billed “obscure” city offices to hide NYPD costs associated with trips to the Hamptons. (See Carl’s earlier Vlog)

The office of current New York City Mayor Michael Bloomberg issued a statement Thursday night stating, “during the Giuliani Administration, we believe that security expenses that were originally paid by the Mayor’s office were ultimately reimbursed by the Police Department.”

Giuliani asserts that he received 24/7 NYPD security as mayor and they followed him regardless of where he went, so there would have never been a need to hide security costs. For budgeting reasons, the mayor’s office would sometimes temporarily pay security expenses after which the NYPD would then reimburse his office, Giuliani explained yesterday. With this latest Bloomberg statement, Camp Rudy can continue to fend off charges of any fiscal impropriety.

Sources in Bloomberg’s office also tell Fox News that they take issue with Politico’s characterization of some of the offices that were billed by the NYPD as “obscure.” While current officials can’t explain why the NYPD would have initially billed offices like the City Loft Board and Office for People with Disabilities for police costs, they assert that the offices fall within the mayor’s budget and are not “disparate” or “obscure.” In sum, if a mayor was trying to cover up costs, he would not use those offices.

But, even as the Giuliani campaign continues to refute any wrongdoing, they are still left tacitly acknowledging the former mayor’s then extra-marital affair with Judith Nathan, whom he would visit on these trips to the Hamptons. (See today’s NY tabs here and here.) Turmoil from his personal life is not quite the part of his New York City record the campaign wants to be discussing with just a little more than a month to go before the first primaries.
