In a controversial move, U.S. Immigration and Customs Enforcement (ICE) agents detained Mahmoud Khalil, a Palestinian graduate student at Columbia University, on charges linked to his involvement in pro-Palestinian activism. Khalil, a lawful permanent resident married to a U.S. citizen, was apprehended following the revocation of his green card by the State Department.

Background of the Arrest
Khalil has been a prominent figure in organizing pro-Palestinian demonstrations on campus, advocating for Palestinian rights and criticizing Israeli policies. His activism has drawn significant attention, both supportive and critical, within and beyond the university community. The arrest occurred shortly after the Trump administration threatened to withhold $400 million in federal funding from Columbia University, alleging the institution’s failure to protect Jewish students from harassment.
Legal Basis and Government Actions
The Department of Homeland Security (DHS) alleges that Khalil’s activities align with Hamas, an organization designated as a terrorist group by the U.S. government. This alignment purportedly violates President Trump’s executive orders aimed at combating anti-Semitism and organizations supporting terrorism. The administration has been actively revoking visas and green cards of individuals it identifies as supporters of Hamas, asserting that such measures are necessary to curb anti-Israel activism deemed antisemitic.
Legal and Civil Rights Concerns
Khalil’s attorney, Amy Greer, contends that the arrest lacked a judicial warrant and was politically motivated, aiming to suppress lawful political expression. Civil rights organizations, including the New York Civil Liberties Union, have condemned the detention as an infringement on free speech and a violation of due process rights. They argue that the administration’s actions represent a broader attempt to intimidate activists and stifle dissent, particularly targeting pro-Palestinian voices.
University Response and Federal Funding Threats
Columbia University is actively seeking to address the potential loss of federal funding, emphasizing its commitment to protecting all students from discrimination and harassment. The university maintains that any law enforcement actions on campus must be accompanied by proper judicial warrants, underscoring the importance of legal protocols and the protection of academic freedom.
Implications for International Students and Activists
Khalil’s arrest has raised alarms among international students and activists, who fear increased surveillance and potential repercussions for engaging in political activism. The administration’s use of artificial intelligence to monitor social media accounts for signs of support for organizations like Hamas has intensified these concerns. Legal experts caution that such measures could lead to overreach and the unjust targeting of individuals based on their political beliefs and associations.
