We don't even know who paid for Dn\uncan's plane ticket. Our government knows but they won't tell us.
Whoever paid for Duncan's ticket probably paid for making sure his family is sequestered.
There was an article early on that reported that Duncan’s ticket was paid for by a company credit card. It was a round trip ticket. The name of the company was not the same as the one that he quit. Whether it was affiliated or not, I don’t know.
