Oh, and her 'source' has released her. She just says it was under duress. Thus, the SP knows who her 'source' was. Notwithstanding, he still wants her under oath before the GJ. Hmmmm. Inquiring minds....
This part you have right. The subpoena refers to what the Appeals Court called a "specified government official" and I got the impression the name was known but not made public.
Incidentally, the New York Times quoted this phrase deceitfully (I think--unless it is phrased this way somewhere else that I'm not aware of) a "specified Executive Branch Official".
