The AP is reporting that Tnoy Snow has given his two weeks notice. His last day is September 14.
His replacement will be Dana Perino - the mouthpiece that stands in for him when absent.
Given his tired looks yesterday, I'm personally not surprised.
I'll try to update as more stuff crosses the wires.
He's still saying this is money related and not related to his on-going battle with cancer.
The preznit will kick off the briefing at 1245 to wish him well.
