That's a story I haven't even attempted to follow. I assume Trump and his people won't sign ethics stuff because they're unethical, but I don't really get the details.
Gotta wonder whats in the papers they are being asked to sign. Why would there be 'negotiations'?
Perhaps there's a clearance problem with some of the picks? Maybe if one has nazi tattoos, white supremacy and medieval tats all over their body, it may be concern?
It's not so much shitface doesn't trust the FBI, it's what they will find that he is afraid of.
