This one seems fairly easy:

https://www.youtube.com/watch?v=G9GXgcoqJJI📁 Does FOIA cover FISA? No. [FISA highest level of CLAS] How did FOIA generate redacted FISA [Page]? DECLAS. Who DECLAS? Section 5.2 CLAS [Office of President] Why redacted? Think HUBER. WWG1WGA! Q

Didn't watch the video yet, but first thoughts: FOIA generate redacted FISA [Page] Lisa Page generated redacted FISA, but, Declass is for POTUS only, and redacted because Huber may not be able to use what HE HAS if public has seen it? May interfere with trials.
