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 University of Southern California's University Park campus has reopened Sunday after a pro-Palestinian tent encampment was cleared out and dismantled, the university said.

All students, faculty and staff must present valid identification, USC said.

New York City Mayor Eric Adams on Sunday defended the police crackdown on college campus protests that have broken out in America's largest city.

"When those protests reach the point of violence, we have to ensure that we use a minimum amount of force to terminate what is perceived to be a threat," " Adams told ABC News "This Week" co-anchor Jonathan Karl.

Adams added that the police intervention resulted from days of communication between the police and school officials.

"We knew we had to get permission unless there's imminent threat to life, or severe threat to property," he said, adding, "We were not going to overstep our legal authority."

When pressed by Karl about criticism, including from some other Democrats, that the response to protesters was disproportionate given that they were largely nonviolent, Adams said, "One has the right to have his or her opinion, and I respect that. ... And I have an obligation and responsibility to ensure the city is safe."

Linda G. Mills, the president of NYU, posted a statement Friday evening explaining why the school called in the NYPD to break up an encampment on the Greene St. Walkway earlier in the day.

Mills said 14 people who refused orders to leave the area were arrested and the incident was non-violent.

The president said that the police were called in for numerous reasons, including noise complaints from nearby residents and businesses, safety concerns over the crowds of supporters and counter-protesters and escalating threats.

"The encampment had become increasingly untenable for the NYU community and the neighborhood we inhabit," she said.

Mills said three senior administrators spoke with the protesters over the weekend to come to an agreement over shutting down the encampment.

The president said things escalated on Wednesday when a group of people from a May Day march came to the walkway and got into altercations.

The May Day incident and other issues, including threats leveled at NYU administrators, led the school to call the NYPD, according to Mills.

"The university’s senior leadership and I were compelled to conclude that we could not tolerate the risk of violence any longer and that we could not responsibly or in good conscience wait until something drastically worse were to happen in order to act. We needed to bring this to a close," she said.
