It was not mentioned anywhere to my knowledge. Everything I saw regarding that time period was chaos in the Dem circles.
I have only been following Q for a few weeks and had to search to find the original.
Ransomnote may know more than I do.
I have yet to see on this thread any disclosure of a secret and guarded meeting the night after the election earlier than November 14. I believe there was not. If we have a sleuth who can provide an earlier mention of it from another source, then I am wrong. If I am right, and the meeting on that date with that number of people, that is hardcore confirmation that Q is an insider. Isn't it?
The informant has that information. Only an insider would be privy to it at this point. And Q knew about it on November 14. How? He must be VERY inside. Top level.
