Which is exactly what they are pushing. If Rove is the source, then Miller is in jail because she didn't want to disclose him as her source.
If anyone believes that, I have several bridges in NYC and the San Francisco area to sell them.
Bingo, and to take it a step further, why wood Rove let Cooper off the hook (so Cooper wouldn't also have to go to jail)in disclosing Rove's name?
