Angered by recent leaks of information about sensitive intelligence operations, CIA Director Porter Goss is redoubling efforts to get his spooks to keep their mouths shut. At staff meetings last week, CIA managers at the agency’s Langley, Va., headquarters told employees that the leaking had got out of control and needed to stop. “They’re exercised about it and are trying to do what they can to clamp down,” a former senior CIA official tells TIME…

there are efforts within the government to identify leakers. The Justice Department is investigating who gave away the NSA secrets. While such probes rarely succeed, the department’s new willingness to subpoen a reporters and their records could change that. And the CIA has a group of mostly retired officers on contract to read news stories that contain classified material and try to uncover their sources. This may be the toughest spook work. Over the years, the unit, nicknamed “the leak chasers” by some agency hands, has been able to finger only a few talkers. But it has an enthusiastic—and active—backer in Goss. He told TIME in June that he had made dozens of leak-investigation referrals. “Virtually every day I can pick up a paper and find somebody who is an anonymous source,” he said. “That is willful. And it seems to me there ought to be a penalty for that.”

It can’t be terribly hard to identify the leakers. One could start by subpoenaing the reporters who published information received from unidentified offficials.
