According to the New York Times…

Ahmad Chalabi, the Iraqi leader and former ally of the Bush administration, disclosed to an Iranian official that the United States had broken the secret communications code of Iran’s intelligence service, betraying one of Washington’s most valuable sources of information about Iran, according to United States intelligence officials.

[edit]

The F.B.I. has opened an espionage investigation seeking to determine exactly what information Mr. Chalabi turned over to the Iranians as well as who told Mr. Chalabi that the Iranian code had been broken, government officials said. The inquiry, still in an early phase, is focused on a very small number of people who were close to Mr. Chalabi and also had access to the highly restricted information about the Iran code.

Some of the people the F.B.I. expects to interview are civilians at the Pentagon who were among Mr. Chalabi’s strongest supporters and served as his main point of contact with the government, the officials said. So far, no one has been accused of any wrongdoing.

Kind of makes you wonder who the F.B.I. is talking to. You can be pretty sure it’s not some low-level staffer. As Josh Marshall notes in Talking Points Memo,

The Chalabi virus was very widespread at the highest levels of this administration. So I’d say it’s possible, though not likely, that the culprit or culprits could be very high-level administration figures, particularly if they turn out to hang their hats in the White House complex rather than at the Pentagon.

And again, need I remind you that if this was happening in a Democratic White House, the Hill would be seething with impeachment hearings.
