Federal agencies under the Trump administration cancelled over $2 billion in research grants to UC professors by systematically screening for keywords like 'diversity,' 'gender,' and 'vaccine hesitancy' that conflicted with administration priorities — and they've now admitted to doing it. The UC legal team is arguing the terminations were unconstitutional, setting up a significant test case over whether federal agencies can use ideological keyword filtering to defund research. This affects thousands of researchers and raises questions about government control over scientific inquiry.
