Staffers at the US National Institutes of Health published a letter of dissent, taking issue with what they see as the politicization of research and destruction of scientific progress under the Trump administration.

Hundreds of workers at the National Institutes of Health on Monday openly protested the Trump administration’s cuts to the agency and consequences for human lives, writing in a sharply worded letter that its actions are causing “a dramatic reduction in life-saving research.

On Monday, scores of scientists at the agency sent their Trump-appointed leader a letter titled the Bethesda Declaration, challenging “policies that undermine the NIH mission, waste public resources, and harm the health of Americans and people across the globe.”
