Copied/vPasted from BBC Red Button (apologies for tyops):

The US government is trying to rehire nuclear safety employees it had fired on Thursday, after concerns grew that their dismissal could jeopardise national security.

The National Nuclear Security Administration (NNSA) workers were among hundreds of employees in the energy department who received termination letters.

The Department is responsible for designing, building and overseeing the US nuclear weapons stockpile.

That needs no comment from me whatsoever.
