Several dozen protesters were detained on UCLA’s campus Monday morning, according to Los Angeles ABC station KABC.

University officials said all classes would be held remotely Monday “due to ongoing disruptions,” and police would be stationed around campus.

Harvard University students who continue to take part in the pro-Palestinian protest encampment at the school will be “referred for involuntary leave,” the university’s interim president, Alan M. Garber, said Monday.

In a letter to the student body, Garber called on protesters “to end the occupation of Harvard Yard,” arguing that the encampment “favors the voices of a few over the rights of many who have experienced disruption in how they learn and work at a critical time of the semester.”

Students placed on involuntary leave “may not be able to sit for exams, may not continue to reside in Harvard housing, and must cease to be present on campus until reinstated,” he wrote.

“As an academic institution, we do not shy away from hard and important questions,” Garber wrote. “There are many ways for our community to engage constructively in reasoned discussion of complex issues, but initiating these difficult and crucial conversations does not require, or justify, interfering with the educational environment and Harvard’s academic mission.”

Emory University in Atlanta announced Monday they will be moving commencement activities off campus, citing "concerns about safety and security."

"Please know that this decision was not taken lightly. It was made in close consultation with the Emory Police Department, security advisors, and other agencies — each of which advised against holding Commencement events on our campuses," Emory President Gregory Fenves wrote in a message to the university.

The commencement ceremonies will now be held in Duluth, about a half hour from campus, the university said.

On April 25, there were 28 people arrested, including 20 affiliated with Emory University, during a protest on campus, according to the school.

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.

President Joe Biden addressed the nation on Thursday saying that free speech and the rule of law must both be upheld.

"We are not an authoritarian nation where we silence people or squash dissent, the American people are heard. In fact, peaceful protest is the best tradition of how Americans respond to controversial issues," Biden said, speaking from the White House.

But, he condemned the destruction of property, shutting down campuses and forcing the cancelation of classes and graduation, saying it isn't peaceful protest.

"Dissent is essential to democracy, but dissent must never lead to disorder or to denying the rights of others so students can finish the semester and their college education," Biden said.

Biden last commented on college protests on April 22 -- before there was an escalation of suspension and arrests at campuses across the country -- at the time condemning antisemitic actions and those who don't understand the plight of Palestinians in Gaza, a message he reiterated Thursday.

"There is no place for hate speech or violence of any kind whether it's anti-Semitism, islamophobia or discrimination against Arab Americans or Palestinian Americans. It’s simply wrong. There’s no place for racism in America," Biden said.
