Federal Grand Jury Subpoenas Times Reporter

New York Times reporter James Risen has been issued a subpoena and will be asked to reveal a source from his book, "State of War," before a federal grand jury on Feb. 7, Mr. Risen's lawyer told the Times this morning.

His lawyer said that Mr. Risen will be asked to reveal a source from a chapter in his book that dealt with the C.I.A.'s failed efforts to infiltrate the Iranian nuclear program.

The material from the book did not, however, make its way into the pages of the Times. Catherine Mathis, spokeswoman for the paper, said that the Times stood strongly behind Mr. Risen but she declined to say why the material never made the paper.
