Students defied Columbia University‘s orders to vacate their pro-Palestinian  protest by 2 p.m. Monday, despite warnings of suspension and after the school’s president said it would not divest from Israel — a demand that has sparked protests on college campuses across the country.

“We have begun suspending students,” Ben Chang, vice president for communications and a spokesperson for Columbia University, said around 5 p.m., about three hours after the deadline passed.

The university had told student demonstrators to vacate by 2 p.m. or else “be suspended pending further investigation” and barred from completing the spring semester.

At the encampment, now in its second week, participants voted nearly unanimously to stay put.

Around 2:45 p.m. — after the 2 p.m. warning time to leave — protesters were seen marching on the quad and chanting “Disclose! Divest! We will not slow, we will not rest!’”

A portion of the encampment has been cleared to make space for the upcoming commencement ceremony for graduates, and picketers are largely sticking to the perimeters of the encampment.

David Lederer, a 22-year-old sophomore at Columbia, walked up to the picket line and began waving a large Israeli flag.
