The CDC and other federal agencies appeared to be racing to meet a Friday afternoon deadline to remove “gender ideology” from their websites, in accordance with a memo from the Office of Personnel Management.

Health researchers began sharing warnings on social media several days ago, urging members of the community to make copies of federal data before the information was removed from the CDC website.
