I pretty much watched the whole thing. The really telling thing to me was that it was known before the election by several folks high in the food chain. The IG said he'd reported it to the Deputy at Treasury in June of last year. Now...how do you suppose the revelation got delayed until now?
Also, the revelation was prompted by a planted question. I'm not certain what the basis for this was as I've seen conflicting stories that Lerner was sick of it and wanted it out to the IRS wanted it out in a controlled manner since the IG report was imminent. Some control.
