As calls have been made for more stringent action from school administrators, there are now calls for President Joe Biden to mobilize the National Guard in order to curb the anti-Israel protests at Columbia University and other colleges across the country.

Sen. Josh Hawley (R-MO) made the demand on Tuesday in a letter to Biden a day after Columbia University switched to remote learning as safety concerns mount for Jewish students in the Ivy League school.

“On college campuses across the United States, Jewish Americans are at risk,” Hawley said in the letter, in which he pointed to how in-person classes were canceled at Columbia University.

Referring to Biden’s passover statement on Sunday in which he criticized the anti-Israel protests, Hawley said, “Now, you must take action to match those words…You must immediately mobilize the National Guard and any other authorities necessary to ensure the safety of Jewish American students and citizens.”

In his statement on Sunday, Biden had said, “In recent days, we’ve seen harassment and calls for violence against Jews. This blatant Antisemitism is reprehensible and dangerous – and it has absolutely no place on college campuses, or anywhere in our country.”

The protests in Columbia and other campuses have attracted criticism from more politicians, especially Republicans in Congress.

“What’s happening at Columbia is outrageous and un-American. No student of any race or religion should have to leave campus because it’s become too dangerous. The universities allowing rampant antisemitism to rage on campus must be held immediately accountable,” House Speaker Mike Johnson (R-LA) wrote in a post on X.

As for Rep. Virginia Foxx (R-NC), who is the chairwoman of the Education and the Workforce Committee, any student and faculty members guilty of harassing Jewish students should be expelled.

Foxx made her thoughts known in a letter to Columbia University President Minouche Shafik on Sunday, saying, “I am gravely concerned by the ongoing chaos at Columbia University caused by the radical, unlawful Gaza Solidarity Encampment, which has now entered its fifth day.”

“Multiple Jewish students have already sought shelter off-campus. Columbia’s continued failure to restore order and safety promptly to campus constitutes a major breach of the University’s Title VI obligations, upon which federal financial assistance is contingent, and which must immediately be rectified. If you do not rectify this danger, then the Committee will not hesitate in holding you accountable,” she added.

Some Democrats have also spoken against the demonstrations, including New York City Mayor Eric Adams and Rep. Jared Moskowitz (D-FL).

In a post on X, Adams wrote, “I am horrified and disgusted with the antisemitism being spewed at and around the Columbia University campus. Hate has no place in our city, and I have instructed the NYPD to investigate any violation of law they receive a report about and will arrest anyone found to be breaking the law.”

“To the Columbia President, DO NOT make the same choice as the Presidents of UPenn and Harvard. Protect your students,” Moskowitz wrote in his post on X.
