paragraph: The Italian authorities provided the FBI with information from wiretaps of Tokhtakhounov's home telephone, part of an investigation into his criminal activities. The FBI said explicit conversations about the scheme had been recorded between Tokhtakhounov and his conspirators, and between him and Anissina, who was born in Russia and skated for France, and her mother. The FBI cited a vivid conversation with Anissina's mother in which Tokhtakhounov assured her that even if her daughter "falls, we will make sure she is No. 1." After the Winter Olympics, a French judge, Marie-Reine Le Gougne, was suspended by the International Skating Union for not reporting pressure she said was put on her by Didier Gailhaguet, president of the French Skating Federation, to vote for the Russian pairs team. She later recanted and said that Canadian officials had pressured her. The ISU later suspended Le Gougne and Gailhaguet for three years. The federal complaint did not describe the possibility of a wider conspiracy or any contact between Tokhtakhounov, or his unnamed co-conspirators, with Le Gougne. "We have alleged no connection between this man with any officials other than with Russian federation officials," James B. Comey, the U.S. attorney for the Southern District of New York, said at a news conference. He said that Tokhtakhounov "reached out to a co-conspirator, somebody connected to the Russian Skating Federation, who did the legwork for him." Maxwell Miller, Le Gougne's lawyer in Salt Lake City, said no evidence of organized crime influence came up in her suspension hearings before the ISU "I think this situation vindicates the argument that we've made all along," he said. "She's a scapegoat and a target of a corrupt system and was unfairly singled out."
