perjury trap

While one may entertain the speculation SP Mueller is so devious he would waylay unsuspecting interviewees, I suspect the reality is SP Mueller simply allowed Corsi, Manafort, et al a blank canvas to paint their story. If they lied, it was by their own hand, unprompted by SP Mueller.

Now one may suppose the "trap" was to allow these slugs a choice in telling the narrative their way.

Corsi has lied so much, he has forgotten which lie he is telling.
