I wish I had the exact post but it really paints a picture of a planned assassination when considering how events unfolded.
It would be interesting to find the date of that post, to compare it with the timing of when Jill decided to speak at the last minute. The fact that the people removed were ones who were loyal to Trump suggests that was not a “coincidence”. If the other agents knew who was loyal and who was not, Cheatle also did.
I wonder if Jill saw Cheatle in person at these times, or if they had to communicate through means that are discoverable. I wonder what the White House logs show.
