The Washington Post is reporting that the investigation has essentially ended into who within the Bush administration leaked the identity of covert CIA operative Valerie Plame. Legal experts and sources close to the case speculated Wednesday that special counsel Patrick Fitzgerald is not likely to seek any criminal indictments. On March 22, Fitzgerald filed legal papers that suggested the investigation was over except for interviews with two reporters who have refused to testify. Fitzgerald’s filing was part of his effort to persuade the court to order the testimony of New York Times reporter Judith Miller and Time magazine reporter Matt Cooper to wrap up his investigation. Miller and Cooper potentially face prison sentences for refusing to testify.
