(CNN) โ The Trump administration is tightening its grip on efforts to quash pro-Palestinian demonstrations on college campuses, even as a protest over the detention of activist Mahmoud Khalil flared at the presidentโs New York City residence and resistance efforts continue in the courts and beyond.
Khalil, a Palestinian refugee๏ปฟ whose green card was revoked over his involvement with demonstrations last spring at Columbia University in New York City, remains in ICE custody in Louisiana. Newly released video posted online Friday by the American Civil Liberties Union showed the moments of his March 8 arrest, captured by his pregnant wife.
After attorneys failed to agree on a timeline for next steps in the case, Judge Jesse Furman set an 11:59 p.m. Friday deadline for Khalilโs legal team to submit a motion for his bail, court records show. The government will then have until 11:59 p.m. on Wednesday to respond.

โWeโre fighting right now to bring Mahmoud home, back to his family, and to have him released from detention, because this is, you know, a clear case of an individual being targeted and retaliated against for constitutionally protected speech, political dissent,โ Brad Parker, one of Khalilโs lawyers and the associate director of policy at the Center for Constitutional Rights, told CNNโs Jake Tapper on Friday.
Trump, whose envoy is trying to negotiate an extension to the ceasefire agreement between Israel and Hamas in Gaza, boasted this week on social media his administration had โproudly apprehendedโ Khalil, adding those who โsupport terrorism โฆ are not welcome here.โ
But the governmentโs case has โno basis in law,โ Khalilโs lawyer told CNN on Friday.
โThey kidnapped this man, this young student, father-to-be โฆ based on an accusation that he has the wrong political ideas, and he has expressed them,โ Donna Lieberman, executive director of the New York Civil Liberties Union, told Sara Sidner.
โItโs an attempt to bully the universities into submission. Itโs an attempt to bully and intimidate students from speaking out, faculty from speaking out, into being quiet and going with the administrationโs program.โ
Protests continued Friday at Columbia University, where administrators now face a raft of challenges, from federal agents on campus and an ultimatum over federal funding, to disciplining some who participated in protests last spring and defending against a lawsuit seeking to block the schoolโs cooperation with a US House probe.
The US Justice Department is now also investigating whether those involved in last yearโs pro-Palestinian protests at Columbia violated federal anti-terrorism laws, Deputy Attorney General Todd Blanche announced Friday.
The DOJ is looking into โwhether Columbiaโs handling of earlier instances violated civil rights laws that included terrorism crimes,โ Blanche told department employees. โThis is long overdue.โ
The department will investigate whether Columbia University was harboring or concealing immigrants who are in the US illegally, Blanche said.
Columbia faces new federal ultimatum
Columbia students are reeling from the presence of federal agents on campus. The universityโs interim president was โheartbrokenโ to announce Department of Homeland Security agents had served two warrants to search two student rooms, she said late Thursday.
โNo one was arrested or detained. No items were removed, and no further action was taken,โ Katrina Armstrong said in an email that also acknowledged โthe immense stress our community is under.โ
โColumbia continues to make every effort to ensure that our campus, students, faculty, and staff are safe,โ she said. โColumbia is committed to upholding the law, and we expect city, state, and federal agencies to do the same.โ
Homeland Security confirmed Friday that ICE agents arrested a second Columbia University student, citing immigration violations related to overstaying her visa.
Leqaa Kordia, a Palestinian from the West Bank, had her visa terminated in January 2022 for lack of attendance and was arrested by local law enforcement last year for her involvement in what the department has described as โpro-Hamas protestsโ at Columbia University.
She was taken into custody on Thursday, according to DHS, although itโs unclear where she was arrested. A separate Columbia student has self-deported to Canada, the agency said.
The Department of Education and other federal agencies also on Thursday sent a joint letter to Columbia administrators outlining preconditions for โformal negotiations regarding Columbia Universityโs continued financial relationship with the United States government.โ
The actions include adopting the administrationโs definition of โantisemitism,โ reforming the universityโs admissions process and eliminating the University Judicial Board, which handles disciplinary actions against those who violate the universityโs code of conduct, according to a copy of the letter obtained by CNN.
The Ivy League school was given a week to comply with Trump administration demands, which followed its threat a week ago to pull $400 million in grants and contracts from the university over its handling of antisemitism on campus.
Columbia announced Thursday it has expelled, suspended or temporarily revoked the degrees of students who during April pro-Palestinian demonstrations barricaded themselves in Hamilton Hall.
Students sue over demands for their records
Meanwhile, Khalil and seven other students on Thursday sued Columbia, Barnard College and the House Committee on Education and Workforce to block the panelโs demands that the universities share school and disciplinary records of โhundreds of students.โ
The lawsuit, backed by the Council on American Islamic Relations, argues that the committeeโs โpolitical agenda is apparentโ and accuses the government of weaponizing โaccusations of antisemitism to attack ideas it ideologically opposes.โ
The federal lawsuit, along with the other developments at Columbia, comes mere days after the Department of Homeland Security said it was working to identify students involved in protests like those at the school across dozens of US colleges. And Trump in January signed an executive order promising to โcombat antisemitismโ on college campuses by potentially revoking visas and directing universities to โmonitorโ and โreportโ on international students and staff.
Building on a tradition of student-led anti-war protests at Columbia, a coalition of students last spring established encampments, held rallies and staged โteach-insโ on campus to protest the war in Gaza. The movement also was tainted by instances of rampant antisemitism, which Khalil disavowed.
โThere is, of course, no place for antisemitism,โ he told CNN in April. โWhat we are witnessing is anti-Palestinian sentiment thatโs taking different forms and antisemitism, Islamophobia, racism (are) some of these forms.โ
Khalil was arrested last Saturday โin support of Trumpโs executive orders prohibiting anti-Semitism,โ the Department of Homeland Security has confirmed.
New video shows Khalilโs arrest
In the first widely released video of Khalilโs arrest, his wife, Noor Abdalla, can be heard begging for information from officers. She also calls someone named โAmy,โ referencing Amy Greer, one of Khalilโs lawyers. Abdalla, who is eight months pregnant, recorded the video, according to a post shared on Instagram by the ACLU.
โYouโre watching the most terrifying moment of my life. This felt like a kidnapping because it was: Officers in plainclothes โ who refused to show us a warrant, speak with our attorney, or even tell us their names โ forced my husband into an unmarked car and took him away from me,โ Abdalla said in a statement provided to CNN by the New York Civil Liberties Union.
Abdalla tries for several minutes to get information from agents on the scene, the video shows. She tells the agents that Greer would like to speak with someone, but the agents do not respond.
At one point, an agent tells her to wait on the sidewalk. Later, one agent appears to get frustrated with Abdalla for being in the street and not on the sidewalk. At the end of the video, the agent drives away.
โThey threatened to take me too, even though we were calm and fully cooperating. For the next 38 hours after this video, neither I or our lawyers knew where Mahmoud was being held,โ she said. โNow, heโs over 1,000 miles from home, still being wrongfully detained by US immigration.โ
In response to CNNโs request for comment on the video, Department of Homeland Security spokesperson Tricia McLaughlin said: โIt is a privilege to be granted a visa to live and study in the United States of America. When you advocate for violence and terrorism that privilege should be revoked and should not be in this country.โ
White House Press Secretary Karoline Leavitt at a news briefing Tuesday accused Khalil of organizing protests that โdistributed pro-Hamas propaganda, flyers with the logo of Hamas.โ
His legal team, however, has noted Leavittโs allegations do not mirror the governmentโs argument in court.
โIt is always interesting to look at what (the administration is) saying outside of court and compare that to what theyโre saying inside court,โ Ramzi Kassem, an attorney who represents Khalil and the founding director of the Creating Law Enforcement Accountability & Responsibility Clinic at City University of New York Law School, said during a briefing with reporters Friday.
โThe reality is that Mr. Khalil completely and vehemently denies doing anything like that. He has absolutely no connections to Hamas, whatsoever,โ Kassem said.
Kaseem added that he believes Khalil should be commended for his role as the negotiator who represented students during talks with Columbiaโs administration at the height of the pro-Palestine protests on campus last year.
โItโs completely clear to anyone who knows Mr. Khalil โฆ that his one and only goal is to get Columbia University to divest from its complicity with Israeli crimes in Gaza and the West Bank,โ he said.
Protesters swarm Trump Tower
The protest, organized by Jewish Voice for Peace, saw demonstrators wearing shirts that read, โNot in Our Name,โ and unfurling banners that read, โJews Say Do Not Comply.โ
The demonstration was timed to mark the Jewish holiday Purim, which honors Queen Esther, โwho used her voice to speak out and demand that the king not commit genocide,โ said an organizer who livestreamed the event.
โWe know our history and we are here to say, โNever again,โโ Jewish Voice for Peace spokesperson Sonya Meyerson-Knox later told CNN of the protest.
โI am here in adherence to what my ancestors taught me because I have been taught what happens when authoritarian regimes start scapegoating people,โ Meyerson-Knox said. โAnd I know that if we donโt speak up today, we will not be able to speak up.โ
