It would be ridicules to assume there were no discussions. What needs be fleshed out is what were the nature of the discussions that had to have occurred. Note, in a separate report, it was said that JJackson Jr’s people contacted Blago in Oct and the subject of a million to his campaign was brought up as an offer for the Senate job. There was mention on the tape of a million so that seems to confirm that happened. So, given the floor being a million, what were the discussions and how were they going to get beyond one million. Since Blago likes to use “campaign chests” as a personal ATM and since the Sun God raised like a billion for his own campaign, I would look into discussions and how campaign contributions may be involved. It would not be difficult for the Sun God’s people to steer a huge donation to Blago as long as his “fingerprints” were not on it.
I think that's where the catch is: the nature of the discussions. Suppose Emanuel is not on the tapes, but he is talked about by others on the tapes?
In that case, Fitz would want to talk to Emanuel, as he said at that press conference the other day: "When someone says something that's on tape, largely they're stuck with it. But when someone says something on tape about someone else, you usually want to do more investigation to verify what it is that happened."
Consider, just for the sake of argument, that you're guilty to some degree, but you're not sure what was said about you, and if it's enough to implicate you. Do you try to talk to all those involved in the conversations, to figure out what was said, before you talk to Fitz? I think you would.
Even if you're not guilty, you'd want to know as much as you could of what was said about you before you talk to an investigator.
Remember, Fitz prosecuted Libby for a lying to an investigator.
