Related in that it concerns the Senate, I thought this 2010 New Yorker piece[1](which I found via the currently-open archives) was extremely interesting, but also troubling. If you have even a passing interest in the ongoing legislative dysfunction, this article should provide you with plenty to think about.

EDIT: I also seem to have trouble getting titles right on submission to HN. In this case, the reason it's even news that this was released is because it had been a secret document in the past. I feel like the edited title removes a crucial piece of information about this story. Even if the content itself is not particularly revelatory, it speaks to a bigger picture (perhaps even more effectively due to its mundane nature) about the almost comical lack of transparency in certain aspects of the governing process.

EDIT2: In trying to think of other words to replace secret, I kind of hit nothing much because most of those words (such as: mysterious, covert, classified, etc.) evoke the same linkbait-y feeling. Not sure if there is really a good replacement choice.
