A group of researchers has initiated a class-action lawsuit against the National Institutes of Health (NIH), the world’s largest public funder of biomedical research. The lawsuit alleges that the Trump administration has implemented a system of political censorship by systematically blocking or canceling research grants that address specific, disfavored topics.

According to the legal filing, the administration is utilizing a list of 235 prohibited keywords to screen and reject grant applications. The plaintiffs contend that this practice prevents funding for essential research across a wide range of fields, including climate change and health equity. The lawsuit argues that by targeting specific terminology—such as "gender" and "racist"—the administration is effectively suppressing scientific inquiry that does not align with its political agenda.

One specific example cited in the complaint involves a study on Alzheimer’s disease, which the researchers claim was designed to identify dementia risks in vulnerable communities. The plaintiffs assert that the administration’s interference undermines the NIH’s mission to support objective, evidence-based medical research. As of this report, the Trump administration has not provided a formal response to the specific allegations regarding the keyword list or the criteria used for grant approval. Because only one side of the legal dispute has been presented in current reporting, the administration’s justification for these grant decisions remains unknown.
