I was just re-reading an article shared by Q in 2018 which proposed a theory that Jeff Sessions was playing 4-D Chess with his decision to use Huber and the IG (+470 attorneys) to investigate Clinton rather than using a Special Counsel.

The article holds up well and is well worth a re-read today! https://bigleaguepolitics.com/heres-jeff-sessions-might-playing-4-d-chess/

In the article, the author claims that then-Deputy Attorney General Rod Rosenstein also got some investigations started related to Clinton:

Much of this was handled by his #2, Rod Rosenstein, who quietly in mid 2017 initiated separate investigations of the U1 scandal and Hillary’s e-mails. Rosenstein also picked up and continued an ongoing FBI investigation of the Clinton Family Foundation, supporting it with offices in Los Angeles, New York, D.C., and Little Rock.

Is there any open-source evidence of Rosenstein having opened these investigations? I can't find anything outside of this article, but perhaps there are some better diggers than me?
