It was a sting. Mifsud planted the information, Halper tried to reap it. When that failed, they set up the meeting with the Aussie.
They tried to make it out to be a crime that he repeated what Mifsud told him. It was phony, Mifsud was working for the FBI. But Pap didn’t know it was phony...
Of course, there is no crime in repeating what an undercover told him. And there is no crime in trying to set up a meeting with the Russians, as Mifsud evidently had asked him to do. In any event, he failed to attract any interest on the part of the Campaign. So it all went no where.
No collusion. No interest in colluding. Had there been interest, even that would not have been a crime. If it was, Hillary would be behind bars.
I agree with everything that you say with regard to this being a sting where bad information was fed by mifsud to Papa. What I do not understand is how Papa got caught in lies. He must be and have been quite naive to think that he would get away with Miss statements to the FBI.
