Commencement ceremonies are being held at colleges and universities across the U.S. As many campuses have been roiled by protests over the Israel-Hamas war, some school administrations have taken steps to contain disruptions during their commencement activities.

University of Michigan’s commencement was held early Saturday with a few interruptions. Ahead of the ceremony, the school had said staff and security officers were ready to respond and that interfering with commencement would not be considered free speech.
