A little known fact. This means that anyone who worked in the White House gave journalists permission to publicly out them as sources on the Plame deal. That means Rove was not a source or they would have outed him at his request.
The only source could be someone who did not work at the White House. It's obviously Wilson who outted his own wife.
The very idea that Wilson's lawyer tried to make it look like Rove had just released him from any confidentiality, when he had it all along (a blanket one according to your report and again when the investigation began and then a reminder to Wilson's lawyer after the judge's ruling) is all one has to know.
They needed to smear Rove, Bush and the Administration and the facts were in the way.
