U.S. Food and Drug Administration employees reviewing Elon Musk’s brain implant company Neuralink were fired over the weekend as part of a broader purge of the federal workforce, according to two sources with knowledge of the matter.

Elon Musk’s Department of Government Efficiency (DOGE) is reportedly firing hundreds of Federal Aviation Administration employees, according to multiple reports and the FAA workers’ union, even as fatal plane crashes continue to mount under President Donald Trump’s administration — including one as recently as Saturday.

The cuts included about 20 people in the FDA’s office of neurological and physical medicine devices, several of whom worked on Neuralink.
