JERUSALEM - Israel's state comptroller has questioned Prime Minister Benjamin Netanyahu over lavish private trips abroad he made that were financed by businessmen, the Haaretz newspaper reported on Friday. It said he was questioned in secret for more than two hours at the start of the week, over an affair which broke out almost a year ago after an investigation by a private television station, Channel 10. According to Haaretz, the questioning was the final phase of the investigation before Netanyahu is presented with the comptroller's report "in a month or two." The disclosure came as Netanyahu prepared to meet in Washington on Monday with US President Barack Obama. Last April, public radio said the prime minister was suing Channel 10 over its allegation that businessmen had paid for lavish trips for him and his family at a time he was a cabinet minister.
