“This was a hit designed to be released during the primaries.”
(1) From whom did Rick Wilson receive the hoax/rumor? He claims it was obtained from an ex-MI-6 agent, but that ex-agent hasn’t come forward to verify or deny Wilson’s claim.
(2) Why wasn’t the “hit” released during the primaries, as Wilson would have certainly wanted, if he had it then?
I can’t answer either question.
You will have to ask Rick Wlson.
