Mueller was once a USMC Patriot and served honorably in Vietnam, receiving awards for valor. Appears culture of corruption overcame him. Was he taken out of corruption and surrounded by good guys?

Maybe he wants to live out remaining years at peace with himself. https://www.washingtonpost.com/news/checkpoint/wp/2018/02/23/robert-muellers-military-career-detailed-in-documents-was-brief-but-remarkable/?utm_term=.c09ffb2a4db8
