It was probably a pretty sweet no-work, big pay position on the Port Authority board that she gave up as a result and now that the whole internet knows what a bitch she is, she’s poison in political circles - Dems have enough trouble raising money with Hillary hanging around...
Commissioners at the Port Authority of NY & NJ actually don’t get paid at all. It’s a political appointment that serves as a resume-enhancer, and to represent the interests of your home state (in this case, New Jersey) with the bi-state agency.
