Senior officials at the U.S. Centers for Disease Control and Prevention told staffers to avoid using seven words such as science-based and fetus in budget-related documents. The backlash was swift and strident; headlines accused the CDC of censoring scientific ideas. Documents recently obtained via two Freedom of Information Act (FOIA) requests indicate the CDC and other executive branch agencies ... quietly implement organized strategies to control the flow and tone of scientific information to the press and the public. Moreover, these practices have been in place under both the Trump and Obama administrations. The techniques being used are much more subtle ... than mere censorship. Two agencies under the Department of Health and Human Services umbrella have erected obstacles to reporters access to federal scientists. And by striking backroom deals with favored journalists, press officers try to get reporters to cleave to an official narrative. Meanwhile government workers at the FDA, are also portraying a ... press-restraining practice as a boon to journalists. In a so-called close-hold embargo - exposed by Scientific American in 2016 - a few select journalists are given early access to information; in return they agree to hold off on publishing until the agency gives the go-ahead, and to let officials choose whom the reporter may speak with before the embargo expires. Collectively, these practices at the FDA and CDC are staunching the flow of important science and policy decisions to the public.
