Heath and Human Services Secretary Alex Azar wrote a memo this week giving him authority over all new rules and banning any of the health agencies, including the FDA, from signing any "regarding the nation’s foods, medicines, medical devices and other products, including vaccines," the New York Times reports.

Why it matters: The story further underscores reporting that health and scientific agencies are undergoing a deep politicization as the Trump administration races to develop a coronavirus vaccine, as Axios' Caitlin Owens reported. Dr. Peter Lurie, a former associate commissioner of the FDA, told the Times the Azar memo amounted to a "power grab."
