Digby: Waiver-ing

Dick Stauber, Matt Coopers lawyer, just made a very good point on Hardball.

Woodward's souce apparently came forward and told the prosecutor about their conversation. Yet Woodward still says that he is under a confidentiality agreement and needs special permission to reveal what he knows. Stauber asks, "if coming forward and admitting something to a US Attorney isn't waiving confidentiality, then what is?"
