Possibility ?The US could still do a deal with Venezuela where Venezuela maintains some ownership of CITGO and the US does a strategic deal for longer term "guarantees" on oil supply.
Complicated and very political yes but still a possibility as there is a stronger long term interest to have this asset still tied to Venezuelan oil supply.
Payout to creditors ( re the auction) still in play with some agreed to valuation between the US and Venezuela.
If the bid values maintain a lower valuation than what is generally considered fair market this may become an option.
