"We had signed a waiver more than a year ago," Attorney Joseph Tate said. "We didn't think this had anything to do with Scooter. I was under the impression from talking to (Miller attorney Floyd) Abrams that she was protecting a number of other sources."
And it soulds like the agreement with Fitzgerald for her testimony about her conversations with Libby will not compel her to talk about the other sources...most likely these other source(s) are the actual original source(s) of the identity leak.
At least her Libby testimony could potentially clear Libby of any obstruction charges.
