The outcome of the case really doesn't depend on whether you saw (by compulsion) a couple of segments he did for the (I guess) highly partisan and propagandistic ABC News two decades ago. His continued employment there for years after whenever those videos you watched were published would seem to indicate that his reputation suffered no serious harm as a result of them, as would his subsequent employment at Fox Business. (It's theoretically possible that Facebook could say he has no good reputation capable of being defamed, but, again, the facts, including those pleaded in the filing if true, would seem to cut against it.) As I said in GGGP, I agree that I'd be surprised if he won, but I think this has some likelihood of going to discovery. With high-profile defendants, documents and depositions are sometimes the goal.
