Investigator Closing in on Rove

The Washington Note reports:

Based on ABC News sources (and our own video camera) it appears that at least two witnesses testified before the grand jury last Friday, both close associates of Karl Rove.

ABC News has learned that one was Susan Ralston, Rove's long-time right hand. The other, per ABC News' Jake Tapper, was Israel "Izzy" Hernandez, Rove's former left hand (and now a top Commerce Department official). It isn't clear if either had been asked to testify before last week.
The biggest two questions in this case now involve just what prosecutor Patrick Fitzgerald has in mind.

First, what makes him interested in Judith Miller? And, second, who is on the list of people he thinks might have committed a crime? The appearances of Ralston and Hernandez suggests at least part of the focus remains on Rove, although his attorney tells ABC News that he still believes Rove is not a target of the investigation.
