64 thousand dollar questions

From my boy Dan:

But today's news raises even more questions than it answers, among them:

* Who told Cheney, and under what circumstances?
* Did Cheney acknowledge his own role when he spoke to prosecutors last summer? If not, could he be indicted himself?
* Did Cheney encourage Libby not to disclose their conversation?
* Did President Bush know about Cheney's role?
* Who leaked this latest development -- and what was their motivation?
* Does this mean the White House will stop blaming reporters for everything? (That one was rhetorical: The answer is no.)

What did the VP know and when did he know it?
