The verbatim quotes I just posted were from newly released declassified testimony from Crowdstrike head Shawn Henry which is (I think) separate from but related to the Brennan revelations declassified by Grenell referred to in the OP.
The documents showing Brennan suppressed intel were declassified by Grenell but to be honest I'm not sure if they've been released or whether it will require an FOIA request to obtain them, I'll check judicial watch for any news on that front.
I think what we know of them thus far comes from reporting not from the primary source documents themselves so I'm not sure if it comes from declassified and redacted testimony or Intel reports.
Furthermore; the DNI report I'm referring to is the one from the Obama era investigation conducted by Crowdstrike for the intel community which concluded with "high confidence," that the Russians hacked the DNC server to aid Trump.
