NEW YORK − Columbia University announced Wednesday that students had agreed to scale down their encampment as protesters across the nation pressed their demands for an end to the civilian casualties in Gaza that have tested the American public's historically ironclad support for Israel.

Columbia student protesters, meanwhile, issued a statement saying the school had made a "a written commitment and concession not to call the NYPD or the National Guard," calling the progress "an important victory for students.”

Rallies and encampments have sprung up on campuses from California to Massachusetts this week, sometimes prompting police intervention. The protesters are calling for an end to U.S. military support for Israel and for eliminating Israeli investments.

The New York chapter of the Council on American-Islamic Relations, a Muslim civil rights organization, called on political leaders and university officials to stop “endangering” Jewish, Muslim, Palestinian and other students who conducting peaceful protests. "Students should not have to risk their reputation, livelihoods or their safety to speak out against a genocide or their university’s complicity in genocide," CAIR-NY’s Executive Director Afaf Nasher said in a statement.

President Joe Biden on Wednesday signed a controversial aid package bill that provides billions of dollars for the Israeli military. Lawmakers who supported the aid have been among targets of the protesters. In Brooklyn, police made arrests for disorderly conduct late Tuesday during a street protest near the residence of Sen. Chuck Schumer, D-N.Y., the majority leader.

Developments:

∎ At the University of Minnesota campus in St. Paul, police made nine arrests and cleared an encampment after the school asked them to take action, citing violations of university policy and trespassing law.

∎ In the Boston area, encampments have been erected at multiple schools including Tufts University, the Massachusetts Institute of Technology and Emerson College.

∎ California's Cal Poly Humboldt in Arcata will be closed Wednesday after pro-Palestinian protesters occupied a campus building, the school announced.

Protests in New York flare:US campuses brace for more unrest over Gaza war

House Speaker Johnson calls for resignation of Columbia president

U.S. House Speaker Mike Johnson called for Columbia University president Minouche Shafik to resign and announced he will visit the college Wednesday. The Republican from Louisiana will meet with Jewish students on campus and host a news conference to discuss "the troubling rise of virulent antisemitism on America's college campuses," his office said.

"What’s happening at Columbia is outrageous and un-American," Johnson said in a post on X, formerly known as Twitter. "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."

Columbia students say they have won some concessions

Columbia student protest organizers said Wednesday the university has conceded to some demands but that the school continues put students at risk of attacks. The statement − issued in response to the university’s campus update on progress in negotiations with student organizers − referenced historic actions of American universities against student demonstrators at Jackson State and Kent State, where authorities fatally shot several students more than 50 years ago.

“Columbia’s reliance on the threat of state violence against peaceful protesters has created an unstable ground for the negotiations process which will continue over the next 48 hours,” the statement said, referring to the deadline the university has issued. “However, Columbia’s written commitment and concession not to call the NYPD or the National Guard signifies an important victory for students.”

Biden signs off on $26 billion in aid for Israel

Biden signed a controversial aid package bill Wednesday that provides, among other things, $26 billion for Israel. Some of the money will provide desperately needed humanitarian aid for Palestinians in Gaza, but more than half will fund unconditional military aid for Israel. Military aid for Israel has been a driving force for the encampments and other protests at universities and elsewhere in the U.S.

In comments at the White House, Biden focused on the humitarian aid and the threat Israel faces from Iran.

"My commitment to Israel... is ironclad," he said, adding that more than $1 billion in aid is for Palestinians facing a humanitarian crises because of "the war Hamas started."

"Israel must make sure all this aid reaches the Palestinians in Gaza without delay," Biden said.

Columbia students agree to remove some tents, university says

At Columbia, student protesters gathered on campus early Wednesday for another day of demonstrations while just outside the gates protesters were chanting in support of the students. Earlier, the school issued a statement saying protesters had agreed to remove a "significant" number of tents, would allow only students to take part in the encampment, would follow city fire safety rules and would "make the encampment welcome to all and (prohibit) discriminatory or harassing language."

"In light of this constructive dialogue, the University will continue conversations for the next 48 hours," the statement said.

A student organizer did not immediately respond to a USA TODAY request for comment on the deal.

Before the school issued its statement, Columbia Students for Justice in Palestine said administrators threatened to bring in police and the National Guard if protesters did not acquiesce to their demands.

"We remain steadfast in our convictions and will not be intimidated by the University's disturbing threat of an escalation of violence," the group said in a statement.

Brown students protest despite threat of disciplinary action

Students at Brown University in Rhode Island established an encampment Wednesday. Large signs announcing "Gaza Solidarity Encampment" and "Brown invests in the Palestinian genocide" were prominently displayed.

The encampment was set up hours after Provost Francis Doyle sent an email to all students warning that encampments are a violation of university police and and that participants could face disciplinary action "up to and including separation from the institution,” The Brown Daily Herald reported. University Spokesperson Brian Clark told The Herald protest becomes unacceptable when it violates safety policies or interferes with "regular operations of the university."

“We have been troubled by reports of violence, harassment and intimidation at some encampments on other campuses, but we have not seen that kind of behavior at Brown," Clark said. "Any such behavior would not be tolerated.”

Scores arrested in Brooklyn protests

In Brooklyn, police made scores of disorderly conduct arrests when a street protest reached a standoff Tuesday night. The protesters, organized by the activist group Jewish Voice for Peace, had gathered at Grand Army Plaza, near the home of Sen. Chuck Schumer, who has led the effort in Congress to provide funds for the Israeli military. The protesters conducted a Seder dinner and demanded a cease-fire in Gaza.

By nightfall, demonstrators sat in the street and led protest chants against Israel and U.S. foreign aid to the country. Police began pulling dozens of people, young and old, off the roadway. Officers handcuffed them with zip ties and loaded them on several buses that lined the street.

"We refuse to let our traditions be used to starve, displace, and massacre Palestinians," the Jewish Voice for Peace said in a tweet during the protest. "Taking seriously the mandate of the Jewish holiday of liberation requires us to show up with everything we have on the doorsteps of those still arming and funding these historic atrocities."

The New York Police Department said officers arrested 208 demonstrators who blocked traffic at Grand Army Plaza.
