THREAD:
1/ @LindseyGrahamSC's #FISA Oversight witness list includes Sean Newell, CES's Deputy Section Chief for Cyber, who probably covered the second portion of the January Primary Sub-source interview. Hypothesis: Newell's interview portion focused on criminal cyber activity. https://twitter.com/senjudiciary/status/1262514330639241217

2/ A month and a half after the PSS interview, Newell was involved in the indictment of 2 FSB officers and Alexsey Belan, who was responsible for the 2014 Yahoo breach and other hacks dating back to 2012. https://www.justice.gov/opa/pr/us-charges-russian-fsb-officers-and-their-criminal-conspirators-hacking-yahoo-and-millions

3/ Notably, Belan was the co-conspirator in the notorious October 2016 Yevgeniy Nikulin indictment that vouched for Nikulin to "Co-conspirator 1", Nikita Kislitsin.

4/ Kislitsin, a Group-IB Exec who lived in the US, was indicted in March 2014, a case recently unsealed in relation Nikulin's (the indictments are basically identical). Curiously, Group-IB has defended him, mentioning that he met a DOJ employee in 2013. https://www.group-ib.com/media/official-statment-gib-cr-16-00440/

5/ Here's the interesting part, after being indicted in 2014 Kislitsin went to the US embassy in Moscow and rolled on Nikulin. Furthermore, Kislitsin informed the FBI about Belan assisting the FSB in building profiles on individuals using Kompromat. Is Kislitsin a CHS and/or PSS?

6/ This brings us back to Newell's cyber-specific presence at the PSS interview and his indictment of Belan, et al. shortly thereafter. Kislitsin was the original source of the Belan/FSB relationship, did he reengage the FBI after Nikulin's indictment? ¯\\_(ツ)_/¯ and read below.
