“And, to be sure, the Trump administration did things that not only were well outside established norms but also undermined the CDC and the entire field of public health. For example, on April 3, 2020, while announcing the agency’s recommendation to wear masks, the president repeatedly emphasized that no one had to wear masks and explicitly said that he personally wasn’t going to wear one.
The administration also pushed for edits to the CDC’s Morbidity and Mortality Weekly Reports, long the primary means for communicating scientific data to other researchers and the broader medical community. These edits were political, designed to downplay the growing number of COVID-19 deaths and support decisions the administration had already made about issues like school reopenings. Emails revealed that members of the Trump administration were accusing the CDC of trying to make the administration look bad by releasing data disclosing the dire nature of the pandemic.
Those kinds of actions by a presidential administration were unprecedented. And they contributed to a loss of morale and a sense within the CDC that everyone just needed to keep their heads down and not make waves. But the political issues weren’t just about what the administration did — they were also about what it didn’t do.
By early March 2020, the CDC had all but disappeared from press briefings on the COVID-19 pandemic. No one in the Trump administration ever explicitly said that the agency wouldn’t be speaking to the public. But, quietly, that’s exactly what happened. By May 2020, the Union of Concerned Scientists could graph the disappearance of the CDC. And this was a completely different situation from what had happened in past pandemics, when presidents let the CDC take the lead.
At the same time, the Trump administration did not seem to facilitate communication between the CDC and outside experts — something the scientists I spoke to said had been the norm for past administrations faced with a public health crisis.”
