Jim Risen is gruff. Attorney General Eric Holder wants to force Risen to testify and reveal the identity of his confidential source on a story he had in his 2006 book concerning a bungled C.I.A. operation during the Clinton administration in which agents might have inadvertently helped Iran develop its nuclear weapon program. The tale made the C.I.A. look silly, which may have been more of a sore point than a threat to national security. But Bush officials, no doubt still smarting from Risen's revelation of their illegal wiretapping, zeroed in on a disillusioned former C.I.A. agent named Jeffrey Sterling as the source of the Iran story. The subpoena forcing Risen's testimony expired in 2009, and to the surprise of just about everybody, the constitutional law professor's administration renewed it - kicking off its strange and awful aggression against reporters and whistle-blowers. Why don't they back off Risen? How can [Obama] use the Espionage Act to throw reporters and whistle-blowers in jail even as he defends the intelligence operatives who tortured some folks," and coddles his C.I.A. chief, John Brennan, who spied on the Senate and then lied to the senators he spied on about it? "It's hypocritical," Risen said. "A lot of people still think this is some kind of game or signal or spin. They don't want to believe that Obama wants to crack down on the press and whistle-blowers. But he does. He's the greatest enemy to press freedom in a generation." Risen points to recent stories about the administration pressing an unprecedented initiative known as the Insider Threat Program.
