Science under siege: NIH accused of politicizing research in billions worth of canceled grants
In a sweeping legal move that’s sending shockwaves through the scientific community, the American Civil Liberties Union (ACLU) has filed a lawsuit accusing the National Institutes of Health (NIH) of orchestrating a politically-driven campaign to defund research tied to diversity, vaccines, gender identity, and more. At stake: more than $2.4 billion in grant funding and the scientific careers of hundreds of researchers.
Filed Wednesday in a Massachusetts district court, the lawsuit represents four researchers and three unions whose members depend on federal science grants. It alleges that the NIH has terminated at least 678 research projects without proper scientific justification — an action the ACLU calls an “ideological purge.”
“These sweeping actions have disrupted crucial research and upended the careers of some of the nation’s most promising scientists,” said Olga Akselrod, senior counsel at the ACLU’s Racial Justice Program.
The lawsuit names the NIH, its director Jay Bhattacharya, the Department of Health and Human Services (HHS), and its director Robert F. Kennedy Jr. as defendants. Both agencies have declined to comment on ongoing litigation.
Politics vs. Science: the research freeze
The terminated projects span a broad range of topics — from breast cancer and Alzheimer’s to HIV prevention and sexual violence in underserved communities. According to the complaint, more than $1.3 billion in awarded funds had already been spent when the NIH began revoking grants. An additional $1.1 billion in expected funding was abruptly cut.
“These aren’t just numbers,” Akselrod emphasized. “This is years of work, massive investments, and potentially life-saving research that’s being discarded midstream.”
The complaint asserts that many of the defunded projects explored topics now considered politically controversial, including vaccine hesitancy, racial disparities in healthcare, and LGBTQ+ health — areas that have increasingly become targets of federal restrictions under the Trump administration’s broader rollback of diversity and inclusion initiatives.
“There’s no transparency, no guidelines, no scientific rationale. Just a shifting political line that researchers are expected to follow,” Akselrod said.
Scientists in limbo
For scientists like Dr. Brittany Charlton of Harvard Medical School, the consequences are personal and immediate. Charlton, who founded the LGBTQ Health Center of Excellence at Harvard’s T.H. Chan School of Public Health, has had five federal grants revoked since February. Her work focuses on health inequities faced by LGBTQ+ individuals — particularly in cancer care and reproductive health.
Another researcher, Dr. Katie Edwards of the University of Michigan, saw six of her projects terminated. Her studies focused on preventing sexual violence, especially among Indigenous and LGBTQ+ youth. Both women are now among the plaintiffs fighting to restore funding not just for their own work, but for what they call a broader principle: academic independence.
A dangerous precedent
The ACLU’s lawsuit is just one of several mounting legal challenges to recent federal policies targeting research funding and diversity programs. In February, a Massachusetts judge blocked an NIH move to slash indirect funding — money used for lab operations, equipment, and staff — that would have crippled universities and institutions nationwide.
Advocacy organizations like the Center for Science in the Public Interest and the Protect Democracy Project are backing the lawsuit, arguing that the NIH’s actions threaten to undermine the integrity of American science itself.
“You can’t turn scientific research on and off like a faucet,” Akselrod warned. “This sets a dangerous precedent — one where politics decides what questions we’re allowed to ask.”
As the legal battle unfolds, its outcome could shape not just the future of scientific research in America, but the very boundaries of academic freedom in a politically polarized era.
