Clearly this isn’t true. Its just the Koch brothers making it up.
I am betting Nero called and told him after hearing of Louis Lerners Attorney’s offer for ammunity to the committee that He (holder) needs to take care of the problem and that holder needs to make sure all traces back to the white hut are erased.
Holder knows the committee already has the communications that tie back to the white hut. They just need Lerner to verify it.
