Russert is the one who has been caught in lies. Why wasn't he prosecuted? He initially tried to make it sound as if he had been called by Libby with a Wilson-related tidbit, although Libby said the conversation had actually been primarily about some other issue (welfare reform policy, IIRC). Russert denied it - and then when his notes were supoenaed, it turned out that Libby was right, and they had indeed discussed the other issue, with anything about Wilson apparently being an afterthought and a bit of digging on Russert's part.
Faulty memory? Possibly. Or possibly intentional misleading of the GJ to make things seem worse for Libby. But because this is Russert we're talking about, nothing happened. On the other hand, Libby is being railroaded with even less evidence.
Remember, any jury in DC is overwhelmingly made up of hard-core Dems, and this is something that has to be taken into consideration in this case.
My contention is that these phone calls to the Whitehouse all went down about the same time "as planned". Consequenly, he told them all "I'm not giving you my source, it's none of your GD business." I might have been done the same. I also would have said: "What the hell is going on" and went on with my work. They're all calling him about the same thing? Well then, they must be talking to each other.
Cooper's call was not logged in because he did not call Rove's office directly. He went through the switchboard. Pretty clever.
Someone wrote me and said that Clinton changed the phone system so "switchboard" calls couldn't be tracked.
