I happened upon a video on my phone last night delineating four criminal investigations Robert Mueller himself is under. However, the search engine won’t direct me to those, and instead always sends to criminal investigations Mueller is conducting, namely into the faux RUSSIA-TRUMP CAMPAIGN collusion. However, I have found this article today.
I will try to track down the video enumerating the four investigations and post it in this thread soon. Or maybe someone posting here can recall it themself. But this article provides the backstory re Robert Mueller and the collusion narrative that the mainstream has not mentioned.
