The Deportation of Mahmoud Khalil: How a Cold War Statute Became the Government's Weapon Against Campus Protest

On April 9, 2026, the Board of Immigration Appeals issued a final administrative removal order against Mahmoud Khalil, a 31-year-old Palestinian-born former Columbia University graduate student who served as the lead negotiator for the Gaza Solidarity Encampment in spring 2024 [1]. The ruling marks the end of the administrative immigration process and moves Khalil one step closer to deportation — though his attorneys say federal court injunctions still prevent the government from detaining or removing him [2].

The decision caps a 13-month legal battle that began when ICE agents pulled Khalil from his Columbia apartment on March 8, 2025, making him the first person publicly arrested in the Trump administration's crackdown on noncitizens who criticized Israel's military operations in Gaza [1]. Khalil, who married a U.S. citizen in 2023 and obtained lawful permanent residency in November 2024, has no criminal record [3]. His case has become the most consequential test of whether the federal government can use immigration law to punish political speech — and the answer will shape the rights of approximately 13 million lawful permanent residents in the United States [4].

The Legal Architecture: A Two-Pronged Attack

The government's case against Khalil rests on two distinct statutory provisions, each carrying different evidentiary burdens and constitutional implications.

The first is Section 237(a)(4)(C) of the Immigration and Nationality Act, codified at 8 U.S.C. § 1227(a)(4)(C), which permits the deportation of any noncitizen "whose presence or activities in the United States the Secretary of State has reasonable ground to believe would have potentially serious adverse foreign policy consequences" [5]. Secretary of State Marco Rubio personally invoked this authority against Khalil in March 2025, issuing what has become known in legal filings as the "Rubio determination" [6].

The statute contains a critical carve-out: it bars deportation "because of the alien's past, current, or expected beliefs, statements, or associations, if such beliefs, statements, or associations would be lawful within the United States" [5]. But that protection has an override — the Secretary of State can personally determine that the individual's presence "would compromise a compelling United States foreign policy interest" [7]. Rubio made that determination as well, though the specific reasoning behind it has not been made public [6].

The second prong emerged later, after Khalil's legal team successfully challenged the foreign policy ground. In a move his attorneys called "retaliatory," the government added a charge under 8 U.S.C. § 1182(a)(6)(C)(i), alleging that Khalil misrepresented material facts on his green card application — specifically, that he failed to disclose his service as a political affairs officer for the United Nations Relief and Works Agency for Palestine Refugees (UNRWA) and his membership in Columbia University Apartheid Divest (CUAD) [8][9].

What Evidence Did the Government Present?

This is where the case becomes most contested.

On the foreign policy ground, the government claimed Khalil's protest leadership was "aligned to Hamas" [1]. But according to the ACLU, the Center for Constitutional Rights, and court filings reviewed by NBC News, the government presented no evidence of any operational or financial connection between Khalil and Hamas [10][11]. An NBC News analysis of government documents found that officials relied on unverified tabloid journalism and made "clearly erroneous" claims about Khalil's work history [12].

A federal district court in New Jersey reached a similar conclusion. In June 2025, Judge Michael E. Farbiarz found that the government's use of the Rubio determination to deport Khalil for his protected speech was likely unconstitutional, and he issued an injunction blocking Khalil's detention and deportation on that basis [6]. "Mahmoud was targeted for his speech," said lead attorney Marc Van Der Hout [2].

On the misrepresentation charge, Khalil's attorneys argue the government produced "no evidence to substantiate" the claim "because no evidence exists" [10]. Internal government documents obtained during litigation allegedly showed officials found no basis for the charge before Khalil's detention — suggesting it was manufactured after the fact to salvage a case that was collapsing on its original grounds [2].

The government's counter-argument, as articulated by supporters of the deportation effort, centers on Khalil's role within CUAD and his alleged distribution of materials bearing Hamas insignia on campus [13]. City Journal, a conservative policy magazine, argued that Khalil's conduct crossed from protected speech into material support for a designated Foreign Terrorist Organization — a distinct deportation ground under the INA [13]. However, no formal terrorism-related charges have been filed against Khalil, and the government's case in immigration court did not proceed on material support grounds [9].

The Evidentiary Standard Gap

Legal scholars have identified a significant gap between what courts have historically required in analogous cases and what was produced in Khalil's proceedings.

Under the foreign policy deportation ground, the Secretary of State need only submit a letter outlining "facially reasonable and bona fide reasons" for the determination [5]. The government bears the burden of proving its allegations by "clear and convincing evidence" in removal proceedings generally [14]. But the foreign policy provision creates a zone of executive discretion that, as the Lawfare Institute's analysis noted, provides "standardless discretion" — a noncitizen "has no way of predicting what ramifications constitute" serious adverse foreign policy consequences [7].

The Supreme Court's decision in Sessions v. Dimaya (2018) struck down a different removal statute as unconstitutionally vague and established that "the most exacting vagueness standard should apply in removal cases" [7]. Whether that holding extends to the foreign policy ground remains an open question that Khalil's case may force appellate courts to answer.

For the misrepresentation charge, the evidentiary standard is more straightforward: the government must show that Khalil knowingly concealed or misrepresented a material fact in his application [9]. But his attorneys contend that CUAD membership and UNRWA employment were not material to his adjustment of status and that the application did not specifically require disclosure of those affiliations [8].

The Immigration Court System: Stacked Odds

The BIA's ruling came as little surprise to immigration law practitioners. The board has historically upheld removal orders at rates exceeding 85%, and data from the Transactional Records Access Clearinghouse (TRAC) at Syracuse University shows that trend has intensified under the current administration [15].

Immigration judges, who serve under the Department of Justice rather than as independent Article III judges, have faced persistent criticism from advocacy groups and some legal scholars over questions of independence. Khalil's attorneys raised this concern directly, requesting that one BIA judge recuse himself due to prior involvement investigating student protesters [1].

Parallel Cases: A Mixed Record

Khalil's case exists within a broader campaign targeting noncitizen pro-Palestinian activists. At least several individuals have faced deportation proceedings under similar legal theories since early 2025, with divergent outcomes.

Rümeysa Öztürk, a Turkish PhD student at Tufts University detained in March 2025 after co-authoring a pro-Palestinian opinion piece in a student newspaper, had her case terminated in February 2026 after an immigration judge found DHS lacked legal grounds for removal [16]. An unsealed State Department memo revealed that officials had no evidence against Öztürk beyond the article she wrote [16].

Mohsen Mahdawi, a green card holder detained at a citizenship appointment in April 2025, had his case dismissed on procedural grounds after an immigration judge determined the government had not properly authenticated the Rubio memo [17]. That ruling was issued without prejudice, meaning the government could refile [17].

The contrast is stark: courts that examined the government's evidence closely found it lacking, while the immigration court system — operating under different procedural rules and standards of independence — sustained the charges against Khalil.

Due Process: What Rights Does a Green Card Holder Retain?

The constitutional question at the heart of Khalil's case is how much due process protection a lawful permanent resident retains when the Secretary of State invokes foreign-policy deportation authority.

The Supreme Court has repeatedly held that noncitizens present in the United States — including lawful permanent residents — possess constitutional rights, including First Amendment protections [4]. In Fong Haw Tan v. Phelan (1948), the Court recognized deportation as "a drastic measure" that involves "forfeiture" of established community ties [7].

When deportation is based on criminal grounds, the process is comparatively well-defined: the government must prove the underlying criminal conduct, the respondent can confront witnesses and challenge evidence, and federal courts exercise robust review on appeal [14]. The foreign policy ground, by contrast, allows the executive branch to rely on a letter from the Secretary of State — a determination that courts have historically given substantial deference [7].

This creates what the ACLU calls a "two-track" system: a green card holder accused of a crime gets more procedural protection than one accused of holding disfavored political views [2]. The Lawfare analysis went further, arguing that LPRs should be excluded entirely from the foreign policy deportation ground absent explicit congressional intent, invoking the "clear statement" doctrine from cases like Ex parte Endo (1944) and Kent v. Dulles (1958) [7].

Khalil's attorneys have asked the full Third Circuit Court of Appeals to reconsider an earlier panel ruling that required the case to proceed through the immigration court system before federal courts could intervene — a decision that effectively delayed judicial review of the constitutional claims for over a year [2][18].

The Campus Organizations Question

The government's case references Khalil's role in Columbia University Apartheid Divest (CUAD), a coalition of more than 120 student organizations formed after Columbia banned its chapters of Students for Justice in Palestine and Jewish Voice for Peace in November 2023 [3]. Khalil represented CUAD as a negotiator and spokesperson during the April 2024 Gaza Solidarity Encampment [3].

CUAD has no documented financial or operational ties to Hamas, Hezbollah, or any organization designated as a Foreign Terrorist Organization by the U.S. State Department [3]. The coalition is a university student organization. The government has alleged that Khalil failed to disclose CUAD membership on his green card application, but CUAD is not a group that triggers any statutory disclosure requirement under immigration law, according to Khalil's attorneys [8].

The government separately cited Khalil's prior employment with UNRWA, the UN agency responsible for Palestinian refugees [9]. UNRWA has faced its own political controversies — Congress suspended U.S. funding in early 2024 following Israeli allegations that some employees participated in the October 7 attack — but it remains a recognized UN agency, not a designated terrorist organization [9]. Working for UNRWA is not itself a ground of deportability.

Supporters of the government's position, including City Journal's analysis, pointed to CUAD statements about "fighting for the total eradication of Western civilization" and alleged that the group sought "instruction from militants" [13]. Khalil's attorneys have characterized these claims as taken out of context or attributed to individuals rather than the organization as a whole [2].

The Steelman Case for the Government

The strongest version of the government's argument does not depend on proving Khalil personally coordinated with Hamas. Rather, it rests on two claims: first, that the Secretary of State has broad, congressionally delegated authority to determine what constitutes adverse foreign policy consequences, and courts should defer to that judgment [13]; and second, that Khalil's failure to disclose material employment and affiliations on his green card application independently justifies removal, regardless of the foreign policy question [9].

On the first point, there is precedent. In Matter of Ruiz-Massieu (BIA 1994), the Board upheld the removal of a former Mexican government official on foreign policy grounds, finding the Secretary of State's determination entitled to deference [7]. The legislative history of the provision indicates Congress intended it to apply "sparingly" in "unusual circumstances" — such as preventing "imminent harm" to Americans abroad or remedying treaty violations [7]. Whether campus protest activity fits within that framework is the central question.

On the second point, misrepresentation on an immigration application is a well-established ground for removal. If the government can show Khalil knowingly omitted material facts, that ground stands independently of any First Amendment analysis. The question is whether UNRWA employment and CUAD membership were material — and whether the charge was manufactured retroactively [8].

How Allied Democracies Have Responded

The United States is not alone in grappling with how to handle noncitizen pro-Palestinian activism. Germany has moved most aggressively among allied democracies.

In April 2025, German authorities ordered the deportation of four foreign residents — including a U.S. citizen, two Irish citizens, and a Polish citizen — for their participation in pro-Palestinian demonstrations [19]. The deportation orders were issued under German migration law, citing the principle of "Staatsräson" (reason of state), under which Israel's security is treated as a German state interest given the historical responsibility of the Holocaust [19]. The four were not convicted of any crime [19].

The European Legal Support Center tracked over 760 cases of repression against pro-Palestinian expression in Germany since 2019, with incidents increasing sharply after October 7, 2023 [20]. More than a dozen Palestinian and Arab nationals had their refugee status or residency revoked because of participation in pro-Palestinian rallies or social media posts [20].

In the UK, France, and Canada, there has been no comparable pattern of deportation proceedings against noncitizens for pro-Palestinian protest activity, though individual incidents of visa denial and entry refusal have been reported [19]. The legal thresholds in those countries generally require evidence of direct incitement to violence or affiliation with proscribed organizations — standards more specific than the "adverse foreign policy consequences" language in U.S. law.

What Happens Next — and What It Means

Khalil's case now moves to the federal appellate courts. His attorneys have indicated they will appeal to the Fifth Circuit Court of Appeals while continuing to press their habeas corpus case in the Third Circuit [2][18]. The federal district court injunction from June 2025 remains in effect, meaning the government cannot physically detain or deport Khalil while that litigation proceeds [6].

The case will most likely reach the Supreme Court [4]. If the removal order is ultimately upheld, it would establish that the Secretary of State's foreign policy authority can be used to deport a lawful permanent resident whose primary conduct was organizing campus protests — a precedent with implications for all 13.3 million LPRs in the United States [4].

Courts have previously placed some limits on executive deportation authority. Kent v. Dulles (1958) held that the Secretary of State lacked authority to deny passports based on political views without a clear congressional statement [7]. Sessions v. Dimaya (2018) struck down a vague removal statute as unconstitutional [7]. Whether those principles extend to shield Khalil remains the central question.

Khalil, who spent 104 days in detention at the LaSalle Detention Center in Jena, Louisiana, before his judicial release in June 2025, has maintained throughout that his only offense was political speech [1]. "The only thing I am guilty of is speaking out against the genocide in Palestine," he said following the BIA ruling, "and this administration has weaponized the immigration system to punish me for it" [1].

His wife, Dr. Noor Abdalla, a U.S. citizen, was nine months pregnant during his detention [10]. If deported, Khalil has said he fears for his life, as a stateless Palestinian who could be sent to Algeria or Syria [9].

The legal questions his case raises — about the boundaries of executive power, the rights of permanent residents, and the line between legitimate national security enforcement and political retaliation — will outlast any single administration's tenure.
