In their race to purge federal workers, Elon Musk and DOGE fired 350 employees at the National Nuclear Security Administration on Thursday without realizing many of the workers played a critical role in maintaining the country’s nuclear weapons arsenal. The fired employees immediately lost access to their email and were locked out of offices. By Friday, the acting head of the agency rescinded most of the firings, but the agency has had difficulty reaching some of the workers. Senator Patty Murray of Washington and Congressmember Marcy Kaptur of Ohio called the layoffs “utterly callous and dangerous.”

The Trump administration has also gutted the CDC’s disease detection unit and fired hundreds of employees at the Federal Aviation Administration.
