I'm not a lawyer and I don't know the specifics of what documents *exactly* that Congress has requested. I do wonder if they requested every email to/from certain executives during a lengthy period (like the batch that got Jon Gruden fired). If they are, I don't blame the NFL for pushing back or refusing to provide them. Unless there is a very specific criminal allegation that is being actively investigated, I'm not even sure the FBI or DOJ even has carte blanche rights to receive and read all emails within a private company. And even though I want the **** I believe went down in Ashburn exposed, and Dan Snyder out of this org, I don't think Congress necessarily has a legit right to use that kind of a broad net.
Then again, I'm not a lawyer. Going to be interesting to see where this goes, but I just have the feeling that if the NFL doesn't want to provide mass emails, there's probably not a judge out there that's going to force them to.
