On Tuesday, an unknown number of CDC staff began receiving emails stating that their letters of termination were being rescinded, according to emails reviewed by NPR and interviews with more than half a dozen sources at the agency who were not authorized to speak publicly.

“As a result, your physical and logical access has been restored and you are cleared to return to work on Wednesday, March 5, 2025” the email states. “We apologize for any disruption that this may have caused.”
