Several nike shox turbo officials identified the official who is under investigation

Several nike shox turbo officials identified the official who is under investigation, but he could not be immediately reached for comment about the accusations.

Neither the official under suspicion nor anyone else associated with the case has been arrested, the officials said. Government officials suggested on Friday that investigators were seeking the cooperation of the Pentagon official being investigated.

Justice Department officials declined to comment on the matter. A spokesman for the Israeli Embassy, David Siegel, denied the accusations of espionage. “They are completely false and outrageous,” he said.

“The United States is Israel’s most cherished friend and ally,” Mr. Siegel said. “We have a strong ongoing relationship at all levels, and in no way would Israel do anything to impair this relationship.”

The American Israel Public Affairs Committee also denied any wrongdoing. The organization said in a statement: “Any allegation of criminal conduct by the organization or its employees is baseless and false.” The group added, “We are fully cooperating with the nike shox turboal authorities and will continue to do so.”
