Columbia University has distributed a letter to members of the encampment on campus telling them to gather their belongings and leave the area by 2 p.m., saying if they identify themselves and sign a form "to abide by all University policies through June 30, 2025, or the date of the conferral of your degree, whichever is earlier, you will be eligible to complete the semester in good standing."

The school said it has "already identified many students in the encampment" and "if you do not identify yourself upon leaving and sign the form now, you will not be eligible to sign and complete the semester in good standing." The school warned it could take action up to suspension or expulsion if they do not leave the encampment.

The school reiterated that negotiations with protesters had broken down and said the protests are a "disruption" to those taking final exams and preparing for graduation.

"As you are probably aware, the dialogue between the University and student leaders of the encampment is, regrettably, at an impasse," the letter states. "The current unauthorized encampment and disruption on Columbia University’s campus is creating an unwelcoming environment for members of our community. External actors have also contributed to this environment, especially around our gates, causing safety concerns – including for our neighbors."

Protesters at Columbia University, who sparked many of the protests across the nation earlier this month, are now being asked to voluntarily disperse after the school's president said it was not able to come to an agreement through negotiations.

Since Wednesday, "a small group of academic leaders has been in constructive dialogue with student organizers to find a path that would result in the dismantling of the encampment and adherence to University policies going forward. Regretfully, we were not able to come to an agreement," Columbia President Minouche Shafik said in a statement Monday morning.

One of the top demands of the protesters, for Columbia to divest from Israel, was flatly denied by the university, according to the statement.

The school asked protesters, who number in the hundreds, to voluntarily disperse, but offered no explanation for what would happen if they did not. The school said it did not "want to deprive thousands of students and their families and friends of a graduation celebration." The school's graduation ceremony is set to be held May 15.

"We urge those in the encampment to voluntarily disperse," Shafik wrote. "We are consulting with a broader group in our community to explore alternative internal options to end this crisis as soon as possible. We will continue to update the community with new developments."

Police cleared out an encampment at Virginia Tech late Sunday after protesters had set up tents on the lawn of the campus' Graduate Life Center.

"Those who gathered were advised by university officials to remove their possessions and to disperse voluntarily; those who failed to comply were then approached by Virginia Tech Police and were again asked to leave and advised that anyone who failed to comply would be charged with trespassing, in accordance with Virginia law," the school said in a statement.

The university added, "At approximately 10:15 p.m., police approached protesters to ask them to disperse within five minutes. Those who remained were subject to arrest."

Dozens of protesters were taken into custody, according to Lynchburg, Virginia, ABC affiliate WSET.

UCLA announced it is instituting additional security measures amid protests on campus over the Israel-Hamas war in a statement on Sunday.

"UCLA has a long history of peaceful protest and we are heartbroken to report that today, some physical altercations broke out among demonstrators on Royce Quad," Mary Osako, vice chancellor of UCLA Strategic Communications said.

"We have since instituted additional security measures and increased the numbers of our safety team members on site," Osako said.

"As an institution of higher education, we stand firmly for the idea that even when we disagree, we must still engage respectfully and recognize one another’s humanity," Osako continued.

Addressing the physical altercations during the protests, Osako said, "We are dismayed that certain individuals instead chose to jeopardize the physical safety of the community."

Last week, the University of California rejected calls to divest from companies that do business with Israel.

Over 300 Harvard University professors have signed a letter to the university urging "constructive dialogue" with the peaceful protesters on campus.

"We are concerned that the university has yet to meet with the students to hear their concerns. Instead, the administration has issued escalating threats of punitive disciplinary action, the severity of which the university has not seen in decades," professors wrote.

"We urge the administration to meet and engage in meaningful dialogue with peacefully protesting students," the letter said.

The letter, sent to interim President Alan Garber and interim Provost John F. Manning Tuesday, came after Harvard warned protesters to empty their encampment. The professors are urging Harvard's administration to follow the lead of Brown University and Northwestern University, where encampments ended after school leadership agreed to take steps toward divestment.

"I think so many of us signed this letter because, as faculty, we have a duty of care towards our students. The harshness and scale of the proposed punishment is unprecedented and frankly alarming; these are activities that should be met with dialogue, not punishment," Teju Cole, a Gore Vidal professor of the practice of creative writing at Harvard, said in a statement.

"We are calling on the administration to be fair-minded and set these protests in the context of numerous other protests that have happened here in the past, in response to which the university did the right thing," Cole said.
