Surely this totally undermines his ability to negotiate in good faith about export restrictions and so on or advise on national security in any capacity. That's not good for the company, shows really poor judgement, I don't see how they can keep him after this. If it was just the affair sure whatever, but it obviously matters that she's an intelligence asset, whether that actually led to anything or not. You can say what you want about export restrictions but his relationship to the US government and the general perception of his judgement matters a great deal for the business.
