In 2015/16 there were a series of high level meetings called for in White House Memorandums which involved a bunch of the bad players we're talking about. Admiral Rogers was involved in some of them as well - so he has first hand knowledge of the doings.
Sorry - DoS FOIA reading room. Use search terms "F-2015-17111" AND "the white house" AND "memorandum for". (The AND must be capitalized). Gauhar, Rybicki, Jarrett, are included in the meetings.
Separate search just on Gauhar yielded 9 results.

>>5140690 TY Baker. You are rockin' it.
>>5140567 As another anon pointed out, occasionally the newest bread in the catalog is one that is being baked. If you end up in such a bread, do not post unless you see a post that says DOUGH followed by a pastebin link.
Otherwise you'll be called all manner of stupid - don't ask me how I know.
