Who said anything about it being a crime? There are many things that aren't crimes that can get you fired.
As long as Americans (and especially Americans in charge of USA) claim to be a Christian nation under God...
You don't know what that means do you...
Evading export controls and lying about it is a crime, falling for a spy is stupid and has tons of potential fall out, having an affair with a direct report is a major liability, I wonder what is next, maybe we will find out more about the connection to the administration next, this season of the leather lothario is wild, will it be the finale, is there another season of fall guy or a full on traitor arc?
No I don't think it is, a breach of contract is a civil matter, not a criminal one. I think it's especially relevant in the case of the CEO of a company, it's certainly common for contracts to be breached, but it doesn't reflect positively on the company.
Marital contracts are not unlike commercial contracts and we are finding out the CEO is in the (non)business of systematically violating them.
