Many colleges accused of tolerating antisemitism on their campuses have been settling with federal civil rights investigators in the weeks before the inauguration of President-elect Donald Trump, who urged a tougher response to campus protests against the war in Gaza. By settling with the Education Department, the schools close the cases against them as long as they meet the terms of the agreements, which mostly have involved training and reviews of past complaints. But many colleges at the center of the highest-profile cases — including Columbia and Cornell — face investigations that remain unresolved and could run the risk of harsher penalties after Trump takes office.
