Mahmoud Khalil, a 30-year-old Palestinian-Syrian Permanent Resident, was arrested by the Immigration and Customs Enforcement (ICE) on March 8, 2025, at his Columbia University apartment as he and his wife returned from dinner. His detention came shortly after he participated in campus protests criticizing Israel’s military apartheid in Gaza.

In Mahmoud’s case, the Trump administration invoked a rarely used section of the Immigration and Nationality Act (INR)—Section 237(a)(4)(C)—to justify his arrest, claiming his presence in the United States was “adverse to foreign policy interests.” Khalil has not been charged with any criminal offense.

Legal Pushback and First Amendment Claims

Shortly after Mr. Khalil’s arrest, the American Civil Liberties Union (ACLU) and other civil rights groups filed a federal lawsuit arguing that his detention violated his constitutional right to free speech. The plaintiffs claimed that the government’s use of the INA provision was vague and exploited to penalize him for expressing his political views, which were protected under the First Amendment.

On April 1, US District Judge Michael Farbiarz paused Khalil’s deportation and agreed to hear the case, marking a significant judicial challenge to how the government applies immigration law in protest-related situations. In his ruling issued on May 28, Judge Farbiarz found the legal grounds used to detain Khalil were not only unconstitutional but also represented a vague framework of jurisprudence that could set a dangerous precedent if employed to target lawful residents over political activity.

The Government Pushes Back

On June 11, the Court ordered Khalil’s immediate release from the Louisiana detention center where he was being held, citing the harm to his family and violation of his free speech rights as the basis of its ruling. His release was swiftly blocked by the Department of Homeland Security, which argued that Khalil should be detained in custody on new grounds. However, on Friday, June 20, Khalil was released, marking a victory for free-speech advocates after months of struggle.

Is Protest Being Criminalized?

Mahmoud’s case raises serious concerns about the ability of the American citizen to hold political opinions that contradict the state narrative. With the lines between national security and political retaliation increasingly blurred, civil liberties organizations, including the Human Rights Watch, have expressed their reservations over how this could translate into a broader crisis for the way ‘dissent’ is treated in the United States, particularly for immigrants and activists. They argue that using immigration law to suppress protest is part of a growing trend to criminalize political speech, especially against US allies like Israel.

The INA Clause, designed to deport noncitizens whose presence is deemed contrary to US foreign interests, was historically used in extreme circumstances. For it to be applied to a student protester is a serious escalation of legal justice, and puts into clear view the federal government’s increasingly authoritarian approach to First Amendment speech.
