Personally, I have found Cates to be open sourced based info with very little speculation, more so now that he writes for Uncover DC and Epoch Times. He can be arrogant at times so a lot of people don’t like him.
As I recall, he made several false claims regarding Mueller and FISAgate. In particular, he a theory that Mueller was a WHite Hat, which he held onto for much longer than any reasonable person would do.
