The official Nvida article only mentions national security concerns and does not bluntly say, as this one does, in its opening:
> admitted to having a romantic relationship with a suspected Chinese spy
> admitted to having a romantic relationship with a suspected Chinese spy
He admitted to having a relationship with a woman.
There's a separate question of whether the woman was a spy.
Whether tabloid, or completely inaccurate, Nvida make reference to it and that there is an independent investigation. It is reasonable for people to wonder what it is about.
I mean, it's pretty clear it was a spy. Have a look at WSJ, NYT, etc. It isn't tabloidish to say so.
