This guy is an "Oathkeeper," from way back. He is no friend of the Democratic Party or its affiliates. He is now experiencing the character attacks form the extreme right-wing that he used to echo. Every public report I read about him is suggests that he is pissed off about what is happening. His loyalty to your cause is being tested. I would not be surprised to see him "turn," and tell someone everything he knows. The only thing keeping him safe, right now, is that the people who really know him, know that he has kept his oath to them.
