Plenty, it seems.
In this doc from the Pentagon's document dump we see a chief Pentagon flak reporting on his attempts to get "potus" to join in on a "closed call" with "our retired military television analysts." The request, he says, had been "submitted to karl and company."
The name of the interlocutor in this email thread has been blacked out. But it's clear he's a close associate of Bush's National Security Adviser Stephen Hadley. He's unable to listen in on the call because he's attending a Hadley speech. He tells the Pentagon propagandist, however, that "I'm hoping to have Hadley brief these guys next week."
At the very least, this shows that officials at the highest levels of the White House -- Hadley and Rove, certainly, and perhaps even the president himself -- were aware of the efforts to "get [the analysts] on message."
Update: I see Glenn Greenwald hit some of these same passages yesterday.
