Both Lindsey Graham and Bill Barr professed particular concern over why Crossfire Hurricane wasn't reeled in as a result of Primary Subsource testimony in Jan 2017 and promised to investigate.

2/ on Apr 27, 2020, Graham made a well-constructed request to DOJ for the key FBI memos and texts that would document FBI's reception of PSS/Danchenko testimony which ought to have raised concern about fraud in Steele dossier

3/ only ONE relevant document has been produced: the EC on the Jan 2017 interview with PSS/Danchenko, which is arguably the single most important document on Russiagate hoax thus far made available.

4/ but DOJ/Graham have produced nothing else responsive to Apr 2020 request, Including:
1a. notes and 302 for Mar and May 2017 PSS interviews;
1b. Intelligence Memorandum circulated by SIA Auten in late Feb 2017 to Priestap and others re Primary Sub-source’s interview.

2. complete Feb 15, 2017, email exchange among Strzok, Priestap and others, in which Strzok stated that “recent interviews and investigation, however, reveal [Steele] may not be in a position to judge the reliability of his sub-source network.”

3. complete Mar 31, 2017, email exchange between OI Attorney and OGC Attorney Clinesmith regarding second FISA Renewal Application and Primary Sub-Source’s credibility. [Note - also concealed in Clinesmith plea]

4. complete email exchange between SIA Auten and OGC Attorney Clinesmith in Mar 2017 referenced in Footnote 389 of the OIG Report. (Not produced in Clinesmith plea either.)

5. the “analytical documents prepared by, or with the assistance of [SIA Auten] after the Primary Sub-source interview” that “identified inconsistencies between Steele and the Primary Sub-source regarding some of the information contained in Reports 94 and 95.”

These documents are all fundamental to Russiagate hoax. While Auten was interviewed by Graham's committee, the transcript is totally uninformative on these important issues - perhaps because DOJ had withheld the documents from Graham or perhaps

perhaps because they were still classified at time of Auten's interview and thus off limits.

Trump's failure to ensure that these documents, already listed by Senate committee, were not rolled out in promised declassification release is one more, but very important, example of both the incompetence of Trump's declassification and intransigence of bureaucratic obstruction
