On Tuesday, an unknown number of CDC staff began receiving emails stating that their letters of termination were being rescinded, according to emails reviewed by NPR and interviews with more than half a dozen sources at the agency who were not authorized to speak publicly.

The CDC issued the frantic appeal on Tuesday after Elon Musk's Department of Government Efficiency (DOGE) cut hundreds of employees from its workforce.

Reports say dozens of laid-off workers received an email that rescinded their terminations and apologized for the disruption caused by the firings.
