Media Blog reader T. McKee wrote to add an important reminder that Bloomberg left out:

In your “Bloomberg Strikes Again” note from today, you quote “Cooper wrote in Time magazine last week that he told the grand jury he never discussed welfare reform with Rove in that call.”
Besides Cooper saying he was working on a welfare story at the time and published something 2 months later, I think the biggest piece of evidence that Cooper did start the call discussing Welfare reform is Rove’s contemporaneous e-mail to Hadley. Per the Washington Times, Rove’s e-mail said:“Matt Cooper called to give me a heads-up that he’s got a welfare-reform story coming,” Mr. Rove wrote Mr. Hadley, who since has risen to the top job of national security adviser. “When he finished his brief heads-up, he immediately launched into Niger. Isn’t this damaging? Hasn’t the president been hurt? I didn’t take the bait, but I said if I were him, I wouldn’t get Time far out in front on this.”This email was dated July 11th. What? Are we to believe that Rove had a crystal ball and knew Cooper would publish a welfare story two months later and Rove just put it in as a cover for potential future grand jury testimony?
It would be interesting to see if this Rove e-mail to Hadley was public before the Washington Times published it on July 17th. I believe Cooper’s testimony was on July 13th. If Cooper knew this Rove e-mail existed, maybe his memory of the Welfare discussion would not have been so blurry!

Excellent take. The earliest press report on the Hadley e-mail that I can find is dated July 15 in Lexis — this AP report by John Solomon — two days after Cooper testified. It was probably leaked to back up Rove. Still Bloomberg hasn’t shown any aversion to reprinting leaked information. I wonder why Bloomberg left this out.
