Columbia University says it has expelled or suspended some students who took over a campus building during pro-Palestinian protests last spring, and had temporarily revoked the diplomas of some students who have since graduated.

Columbia University announced Thursday it's discipling students involved in the occupation of a campus building during protests against the Israel-Hamas war last spring. The big picture: The move comes after the Trump administration last week pulled some $400 million in federal grants and contracts from the university over allegations of antisemitism and after federal agents arrested a Columbia protest leader.
