President Donald Trump’s National Institutes of Health director says some employees’ critical letter to him has “fundamental misconceptions about the policy directions the NIH has taken.”

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.
