On FNC tonight John Gibson said at the My Word segment that Fox contacted their sources (two) who confirmed that Berger was seen stuffing documents in his socks.
Let's use our common sense. If you want to hide 50-60 pages of documents on your person, how could you do it? Perhaps you could fold them in half and place them in an inside coat pocket. You could pretty easily slide them down your pants (pretty uncomfortable). It's also not hard to imagine shoving them two or three inches down into your socks which would hold the papers snugly against your calf.
The one thing you aren't going to do is try to put them in a pants pocket! Way too obvious. That's how we know he's lying.
