Former President Trump slammed Columbia University for closing its campus amid violent anti-Israel, pro-Gaza protests, urging the college to "gain a little strength" and "courage" while saying the move "means the other side wins."

Trump took reporter questions in Trump Tower on Tuesday evening before a meeting with former Japanese Prime Minister Taro Aso, who is the current vice president of the Japanese Liberal Democratic Party. 

COLUMBIA UNIVERSITY MOVES TO HYBRID LEARNING ON MAIN CAMPUS AMID ANTISEMITIC PROTESTS

"Well, we have a lot of different things, but what’s going on with the colleges — and they’re closing Columbia now? I mean, it’s just crazy," Trump said. "Columbia should gain a little strength, a little courage and keep their school open."

Trump’s comments came after students at Columbia University were instructed that classes had shifted to virtual or hybrid amid ongoing safety concerns stemming from the anti-Israel protests filling the campus.

"It’s crazy because that means the other side wins," Trump said Tuesday. "When you start closing down colleges and universities — that means the other side [wins.]"

The former president, pointing to Aso and Japan, said, "In Japan, they don’t know about that. They don’t close. They keep it open. They make it work." 

"The people running Columbia have made a grave mistake," Trump said.

IVY LEAGUE ANTI-ISRAEL AGITATORS' PROTESTS SPIRAL INTO 'ACTUAL TERROR ORGANIZATION,' PROFESSOR WARNS

The announcement comes amid continued antisemitic protests on the New York City campus and just a day after classes were made virtual on Monday.

The guidance, signed in tandem with Chief Operating Officer Cas Holloway, also affects faculty and staff.

The guidance also comes amid days of protests at Columbia, where anti-Israel agitators initially formed an encampment — setting up tents and refusing to leave — on the campus last week. The protesters have marched in and around the campus demanding the school lose affiliations with groups that support Israel amid its war with Hamas in Gaza, which has reportedly resulted in tens of thousands of civilian deaths.

"I am deeply saddened by what is happening on our campus," Shafik wrote. "Our bonds as a community have been severely tested in ways that will take a great deal of time and effort to reaffirm. Students across an array of communities have conveyed fears for their safety and we have announced additional actions we are taking to address security concerns. The decibel of our disagreements has only increased in recent days. These tensions have been exploited and amplified by individuals who are not affiliated with Columbia who have come to campus to pursue their own agendas."
