> AFAICT, Congress hasn't ever been briefed on the day-to-day of wartime activities.

But they're also not normally briefed on the high-level view of intelligence sources and methods, to ensure that those sources and methods remain available. During WWII it's not like the Navy briefed Congress that they could read much of the Japanese Navy's messages.

And even with that precaution the U.S. Navy came perilously close to tipping off Japan. A journalist embedded with Naval forces somehow gained information that the U.S. Navy had known Japan's fleet composition at Midway before the battle, and that was published in the Chicago Tribune. If Japan had been paying attention she would have realized that her ciphers were very possibly being read and taken countermeasures that would have destroyed the usefulness of that intelligence source.

To be clear, I think Congress has the right to have access to whatever information is needed to effectively oversee the NSA. But I don't see how that would imply all 535, every 2 years, being read-in to full TS and SAPs and given all details. That would make more sense for the specific subcommittee charged with overseeing intelligence, but unfortunately (for privacy advocates), that's the very same panel of people most supportive of NSA.
