Where did you hear that? I haven't seen anything other than she was jailed by the SP for not releasing her source.
She (and another NY Times reporter) appear to be implicated in a tipoff to an Islamic terroris.., er, "Charity" that was to be raided by the Feds. This Rove thing is a diversion from that matter...
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....
Separate grand jury into the Islamic Charity business. Miller's testimony for this grand jury is about Plame, Wilson and Niger.
