The U.S. Supreme Court, in a narrow 5-4 decision, has allowed the Trump administration to proceed with rescinding approximately $783 million in National Institutes of Health (NIH) research grants linked to diversity, equity, and inclusion (DEI) initiatives. This ruling lifts a lower court injunction that had blocked the administration's cuts to these grants, which also included funding related to LGBTQ studies. The decision represents a key development in the administration's broader campaign against federal DEI policies. While the Court found that the administration had overstepped in some aspects of its new rules barring NIH from approving DEI-related grants, it ultimately permitted the termination of these specific grants. The ruling has drawn criticism from some lawmakers and scientific communities who argue that the cuts will hinder vital medical research and innovation, including studies on diseases such as Alzheimer’s and breast cancer. The Supreme Court's decision also effectively blocks efforts to reinstate nearly $2 billion in NIH grants that had been targeted for cancellation. The case underscores ongoing tensions over federal funding priorities and the role of DEI principles in scientific research.
