As of October 2023, there are no official reports indicating that former President Donald Trump has initiated mass layoffs at U.S. health agencies such as the Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), or the National Institutes of Health (NIH). Additionally, Donald Trump is not the current President of the United States; President Joe Biden has been in office since January 2021.
Robert F. Kennedy Jr. is not serving as the Health Secretary. The current Secretary of Health and Human Services is Xavier Becerra, who was sworn in on March 19, 2021. There have been no announcements regarding mass layoffs or significant staffing changes at these agencies under the current administration.
If there have been developments after my last update in October 2023, I recommend checking reputable news outlets or official government websites for the most recent information.
