The White House is working on an executive order to fire thousands of U.S. Department of Health and Human Services workers, the Wall Street Journal reported on Thursday, citing people familiar with the matter.

Managers across the health agencies were tasked with categorizing their probationary workers to determine those who were not mission critical, according to two new media reports citing internal sources.

The executive order could come as soon as next week, if the Trump administration goes ahead with plans, according to people familiar with the matter.
