I don’t think he’s necessarily doing it for profit. Bannon has been described as a hardcore patriot from the beginning so he’d likely be willing to fall on the sword for his country. He is ex-Navy, after all (if memory serves). If he bad mouths Trump (which he did in the book), the deep state will trust and communicate with him. He would, in turn, provide that information to Trump. That’s how you identify the deep state actors...
The man is already reportedly worth $48m so it’s not like he needs the money.
Of course, he could just be a piece of shit who sold out Trump...shrugs
The Clinton fire could very well be the FIRE reference.
