The ideological cancellation of $800 million of scientific research grants because they supposedly focused on DEI was just backed by the Supreme Court. This is horrific on so many levels.
Supreme Court allows NIH to stop making nearly $800M in research grants for now
But the court, in its emergency docket order, also left in place by a 5-4 order a lower court ruling that threw out NIH memos that enforced the administration's policies.
