This document was fought hard for, as it was finally released in a heavily redacted form, after a FOIA appeal.
I requested it in September of 2017, and it was denied in its entirety by the NRO as they claimed it was classified due to national security, or FOIA exemption (b)(1).
On October 21, 2017, I filed an appeal to their decision, referencing the fact that it was unlikely the entire document was “classified” as they stated. I believed that there should be at least some releasable portion of this document, whether it be as simple as the cover page, the table of contents, the index, the references section, etc. Some/most of which may not fall into the (b1) and/or (b)(3) exemption categories as they cited as their reason for denial.
On March 16, 2018, the NRO sent me the record as my appeal was partially granted. Though the end result was a highly redacted document, just as I suspected, some portions could be released.
