The U.S. Department of Justice has issued a new subpoena to a New York Times reporter to reveal his sources for a 2006 book on the CIA. The reporter, James Risen, has been ordered to testify at the trial of former CIA officer Jeffrey Sterling. Prosecutors believe Sterling gave Risen information for a chapter on the CIA’s role in disrupting Iran’s nuclear program. In a motion filed this week, prosecutors argued Risen is not exempted from testifying about confidential sources in a criminal proceeding and that he must provide information “like any other citizen.” A federal judge threw out a similar subpoena leveled at Risen last year.
