Back in the United States, Republican presidential hopeful Rudy Giuliani is facing new questions over hundreds of thousands of dollars in questionable billing expenses during his time as mayor of New York City. The Politico newspaper is reporting Giuliani billed several obscure agencies for costs related to his visits to the Hamptons, where he began his affair with future wife Judith Nathan. Hotel, gas and other expenses were charged to city agencies tasked with aiding the disabled, providing public defenders, and regulating loft apartments. Giuliani’s campaign denies he tried to hide the expenses.
