"If Matt Cooper is going to jail to protect a source it's not Karl he's protecting."
The New York Times continues:
"That provided an opening, Mr. Cooper said. 'I was not looking for a waiver,' he said, 'but on Wednesday morning my lawyer called and said, 'Look at The Wall Street Journal. I think we should take a shot.' And I said, 'Yes, it's an invitation.'
In court shortly after 2, he told Judge Thomas F. Hogan of the Federal District Court in Washington that he had received 'an express personal release from my source.'
That statement surprised Mr. Luskin, Mr. Rove's lawyer. Mr. Luskin said he had only reaffirmed the blanket waiver, in response to a request from Mr. Fitzgerald."
The 'express personal release from my source' appears to be Luskin's unnecessary bloviation to the Wall Street Journal. Cooper seems to have decided that he wouldn't allow Rove's attorney to gloat in the protection provided by Cooper's silence, particularly if that silence resulted in the personal cost to Cooper of going to jail. It would be funny if Karl Rove has to resign due to a malfunction in his lawyer's testosterone patch.
