What's up with Scott McClellan

The Washington Post's Jim VandeHei talked about the Plame investigation in a Live Online session yesterday (my emphasis):

Scott McClellan was either lying or was lied to about Rove's involvement in the Plame affair. If Scott is a good guy he should resign instead of working for liars. If he lied, the media should shun him. But instead the media plays the game. 'Scott's a great guy'. Once again, a lie is made and no one is held accountable. If the media does not begin to look for truthful sources, the people of this country will shun the media.

Why isn't Scott giving the briefings down in Crawford? He hasn't done a briefing since August 3rd.
