New evidence has emerged exposing a U.S. campaign to spy on Israeli officials inside the United States. Details of the spy effort are coming to light in connection to the case of former FBI translator, Shamai Leibowitz, who was sentenced to 20 months in prison last year for leaking classified information. The recipient of the information, the blogger Richard Silverstein, has spoken out for the first time about the leaks. In an interview with the New York Times, Silverstein said Leibowitz passed on secret transcripts of conversations caught on FBI wiretaps of the Israeli embassy in Washington, D.C. Those overheard by the eavesdroppers included American supporters of Israel and at least one member of Congress. Silverstein said Leibowitz released the documents because of concerns about Israel’s aggressive efforts to influence Congress and public opinion, and fears that Israel might attack Iran.
