...who sent him doesn't matter. Really it doesn't. It has little to nothing to do with the situation.
A reporter was going to print (according to what I've heard) that the request to go to Niger was made by VP. Rove called and said that wasn't accurate, his agency wife did. (dunno how he would have ever gotten that idea since Wilson was so up front about it however).
But, at same time someone else, apparently (or before per Rove testimony) called Novak and dimed her out.
Regardless, Rove was id'd as a "double secret source" aka >leak< and should be fired for it (cause W said he would and it will make the Dems happy).
