That's a very good one. If Holder says his people didn't tell him, then it's not logical that his people would have told Congress. I'm about to agree with the leftists that Issa must have known, because that means Holder knew. Minor embarrassment for Issa = jail time for Holder.
I saw a while back that one of the main defenses of Gunwalker would be to confuse the original program with the Obama modification that allowed the straw purchases and let the guns walk. The program used to be about tracking crime (illegal purchases) after it had occurred, not allowing crime to happen in the first place.
Indeed it is good. If we know the content of that briefing from the Congressional Record, then Holder is busted, and on paper. This should be in an email to Issa.
