College protests updates: Police begin dismantling University of Chicago encampment

Columbia University announced Monday it will not hold a campuswide commencement ceremony on May 15 as originally scheduled.

Columbia will focus on the smaller, school-based ceremonies instead based on "input and feedback from student leaders," the school said.

"Our students emphasized that these smaller-scale, school-based celebrations are most meaningful to them and their families," the school said in a statement. "They are eager to cross the stage to applause and family pride and hear from their school’s invited guest speakers."

The smaller school ceremonies will begin on Friday. Columbia said it may hold "a festive event" on May 15 instead. Security concerns were among the reasons the larger ceremony was canceled.

One of the reasons Columbia said it had called in the New York Police Department last Tuesday was in order to make room for the schoolwide ceremony in the same location as the encampment.

UCLA Chancellor Gene Block announced Sunday that the university is taking several immediate steps to increase campus safety following protests that prompted the closure of the school last week.

Block said the newly created Office of Campus Safety will oversee the management of the UCLA Police Department and the Office of Emergency Management. The administrative vice chancellor was previously in charge of the agencies.

Rick Braziel, the former Sacramento chief of police, will head the new Office of Campus Safety, Block said. Braziel will report directly to Block.

Additionally, Block said he has created a formal advisory group of safety experts who will partner with Braziel, including U.C. Davis Police Chief Joh Farrow; Vickie Mays, professor of psychology and health policy and management at UCLA, and Jody Stiger, the U.C. Office of the President systemwide director of community safety.

"In the past week, our campus has been shaken by events that have disturbed this sense of safety and strained trust within our community," Block said in a statement Sunday. "In light of this, both UCLA and the UC Office of the President have committed to a thorough investigation of our security processes. But one thing is already clear: To best protect our community moving forward, urgent changes are needed in how we administer safety operations."

The school announced that employees are expected to resume work on Monday and faculty are "encouraged to resume in-person instruction as soon as possible."

Some instructors are being given the option of conducting courses remotely at their discretion through May 10 "without the need for departmental authorization.

"A law enforcement presence continues to be stationed around campus to help promote safety," school officials said in a statement.
