If I'd known specifics off the top of my head, I'd have posted them, lol.
But, what I am recollecting was at Los Alamos, and involved the eventual deportation of Chinese nationals. I'll look to see what I can find, to flesh that out.
No worries.
I recall the general case and was appalled at the access grated by the DOE.
DOE operates under its own rules when it comes to clearances and access, but some things should not be waived-—like when dealing with Chinese (or muslimes).
