Prudish about affairs with spies? Or about affairs with people who, if they break off the relationship could lose their jobs (or if they continue it they could get promoted)?
These aren't just affairs.
Also, fraud remains to be seen, and shopping chips to China sure seems like questionable judgement.
I think you are too narrowly focused.
I don't think that the US *care* about spies? Look who has been put in charge of the NSA, FBI. There's even someone who is strongly suspected to be a Russian spy working in the Pentagon.
These shipments to China - I remember there being a deal made with the President which allowed these sales to happen contingent on some kind of "risk fee" being paid.. to the President.
When you engage in an affair with a superior you have more leverage than you think. Yes you could lose your job, but if you lose your job you have nothing left to lose and can fuck up their life if you have the right evidence.
