Well, I don't know, but I do know Gauhar is deep deep state - operated at the heart of the DoJ coup. When I first encountered the name many months ago I did a deep dive only to discover that the web had been scrubbed. I found an early photo of her in the govt employee web files and posted it on this Q thread... it immediately disappeared from the web. There is one other web site that found it and posted it; I am on my tablet and have no link right now.
What the pen does point to is Gauhar National Security Division Clinton email FISA. I would look for developments there possibly in the Flynn case. Atty Sidney Powell has said that Judge Sullivan's delay does have one silver lining: she is obtaining more incriminating documents.
Aha! So it was “Clinton email” on the letter.
