Mahmoud Khalil, an Algerian citizen of Palestinian origin, was arrested on Saturday by U.S. Immigration and Customs Enforcement (ICE) at his Columbia University-owned apartment in upper Manhattan, New York City.
Khalil, a recent graduate of Columbia’s School of International and Public Affairs, has been a prominent figure in pro-Palestinian activism on campus, including his involvement in the Gaza Solidarity Encampment. In 2024, pro-Palestinian student encampments emerged across the U.S. as part of widespread protests against Israeli military actions in Palestine. These encampments were central to a student-led movement urging universities to divest from companies supporting Israel.
As a legal permanent resident of the U.S., Khalil has been a vocal advocate for these causes. His arrest has sparked widespread outrage, raising concerns about free speech, immigration policies, and the targeting of activists.
Khalil’s activism made him a visible target amid escalating tensions over campus protests and the Trump administration’s crackdown on activities it labels as “anti-American.”
Reasons for Khalil’s Detention
Khalil’s arrest followed an executive order by former U.S. President Donald Trump targeting what he described as “pro-terrorist, anti-Semitic, anti-American activity” on college campuses.
“We know there are more students at Columbia and other universities across the country who have engaged in pro-terrorist, anti-Semitic, anti-American activity, and the Trump Administration will not tolerate it,” Trump stated.
Authorities initially attempted to revoke Khalil’s visa but later discovered he is a permanent resident. They then moved to revoke his green card, with the Department of Homeland Security accusing him of activities “aligned with” the Palestinian group Hamas.
Secretary of State Marco Rubio defended the action, stating, “Coming to the United States on a visa is a privilege, not a right,” and accused Khalil of supporting Hamas. Trump described Khalil’s detention as “the first arrest of many,” signaling a broader crackdown on pro-Palestinian activism.
Additionally, Trump has criticized Columbia University, questioning its efforts to prevent what he calls antisemitic incidents. Earlier this month, his administration canceled $400 million in federal grants and contracts to the institution.
Judicial Process
Khalil was initially detained in New Jersey before being transferred to the LaSalle Detention Center in Louisiana, a facility known for housing immigration detainees.
A federal judge temporarily blocked his deportation on Monday. Judge Jesse Furman ordered that Khalil not be removed from the U.S. until further court proceedings, emphasizing the need to preserve jurisdiction over the case.
During a hearing on Wednesday, Furman also granted Khalil access to his legal team after attorneys raised concerns about limited communication. A separate hearing is scheduled for March 27 in immigration court to determine the validity of Khalil’s green card status.
Justice Department lawyers have argued for the case to be moved out of New York, proposing New Jersey or Louisiana as alternative venues.
Reactions to the Detention
Khalil’s arrest has drawn widespread condemnation from human rights organizations, lawmakers, and activists.
The American Civil Liberties Union (ACLU) called the detention “unprecedented, illegal, and un-American,” accusing the government of targeting individuals for their political views.
Agnes Callamard, Amnesty International’s Secretary General, described the arrest as “deeply shocking” and a violation of fundamental U.S. values, including freedom of expression. The United Nations also emphasized the importance of upholding the right to peaceful assembly and free speech.
Lawmakers, including Senator Bernie Sanders and Representatives Rashida Tlaib, Ilhan Omar, and Ayanna Pressley, have condemned the detention. Sanders called it an illegal attempt to suppress political dissent, while 14 members of Congress signed a letter demanding Khalil’s release, labeling his arrest a “direct assault on freedom of speech.”
Protests have erupted across the U.S., with over 1,000 demonstrators gathering in New York City on Monday to denounce the arrest as political persecution. Protesters criticized the administration’s efforts to silence dissent, with one stating, “The U.S. is enacting many laws and executive orders to prevent us from expressing our opinion, from defending Palestinians, from defending human rights.”
Trump’s border czar, Tom Homan, also faced protests during a visit to New York State’s capitol, Albany. Demonstrators, including assemblyman Zohran Mamdani, criticized Homan’s role in implementing harsh immigration policies and the detention of Khalil.
On Thursday, hundreds of activists staged a sit-in at Trump Tower in New York City, resulting in nearly 100 arrests.
Broader Implications
Khalil’s case has become a flashpoint in the ongoing debate over free speech, immigration, and national security. Critics argue that the Trump administration is using immigration enforcement to target political opponents and suppress activism, particularly on college campuses.
The case also highlights the administration’s broader efforts to restrict pro-Palestinian advocacy, which has surged in response to Israel’s military campaign in Gaza. The conflict has resulted in over 48,500 deaths, mostly women and children, and widespread destruction, with accusations of genocide.
The outcome of Khalil’s case could set a precedent for how the U.S. government handles similar situations in the future, with significant implications for free speech and immigration policy.
Meanwhile, Khalil remains in detention, separated from his wife, an American citizen who is eight months pregnant, and faces an uncertain future.
