With the NSA, getting to the truth takes time. At first, there are mere hints that the agency is spying in some way that would be controversial. Gradually, the public gets circumstantial evidence. The truth becomes obvious to the small percentage of Americans who are paying close attention, but there's no way to prove it.
Finally, the proof arrives! But even though the mere prospect used to be alarming, confirmation is now treated as no big deal: "Oh, everybody knew that already."
We're having one of those moments.
The NSA collects and stores information on phone calls made by members of Congress! Doing so gives the executive branch control of information that could be used to discredit multiple legislators on the theory that it will never be abused. This is imprudent. If I could have reported it as fact five years ago, it would've been a huge story. Now, the revelation is treated as no big deal.
"Because c'mon, haven't we known for awhile?"
Last month, when Senator Bernie Sanders asked the NSA if it spies on Congress, he couldn't get a direct answer. I noted then that the NSA does spy on congressional phone calls—that's what inevitably happens when you spy on virtually every phone call—but that acknowledging as much would unnerve Americans.
