Another Leak Probe?

Josh Marshall notes that a Newsday article about Chalabi contains this very pregnant sentence:

An intelligence source confirmed to Newsday reports in Time and Newsweek that the FBI had launched an investigation into who in the administration had passed the classified material to [Chalabi’s] Iraqi National Congress.

Marshall notes, correctly, that the ramifications of this leak may go far beyond those of the Plame investigation. After all, the intelligence leaked this time may have ended up in the hands of Iran.
