Expense reports filed by Spitzer's campaign committee show plenty of far-flung travel, but nothing in them overtly suggests he was taking prostitutes along or making frivolous jaunts as an excuse to be alone in a hotel room.
There are no payments from the committee to any companies that have been identified by federal authorities as fronts for prostitution.
The committee's lawyer, Kenneth Gross, said he has seen no evidence that the organization paid for hotel rooms for people who weren't on legitimate campaign business.
"We had a really good system, and we carefully reviewed not only the contributions coming in . . . but also on the expenditure side," Gross said.
Spitzer's state-issued credit card also shows no outward sign of having been abused for extracurricular pursuits.
Between September and February, the Democrat charged $4,056 in travel-related expenses to the state, including three trips to Washington, D.C., and another to a conference with Hispanic lawmakers in Puerto Rico. But he did not use his state card to pay for the two rooms that FBI agents accuse him of using to arrange a Feb. 13 encounter with a call girl named Kristen at Washington's Mayflower Hotel.
Spitzer's campaign didn't pay for the rooms either, suggesting that the governor paid with his own money.
That doesn't mean taxpayers were spared any expense associated with the trip; records filed with the state comptroller's office show that the government paid Spitzer's airfare and for hotel rooms for two aides and two State Police troopers who accompanied him on the trip - all at a cost of about $1,070.
The governor's official business in Washington that week was testifying before a congressional committee about problems in the bond insurance market.
Spitzer has told aides and his legal team that he never spent public or campaign dollars on prostitutes. The scandal collapsed his career last week, just days after the married father of three was identified by federal authorities as "Client 9" of the prostitution ring.
Even if authorities find that Spitzer had trysts in hotel rooms that were paid for by his campaign, a prosecution may be difficult. Using campaign money for private purposes is illegal, but candidates are generally given wide leeway on spending that may have a dual purpose.
