A Mosque Leader's Release and the Widening Legal Battle Over Immigration Detention

Salah Sarsour, a 53-year-old Palestinian-born legal permanent resident and president of Wisconsin's largest mosque, was released from an Indiana jail on June 18, 2026, after a federal judge ordered his release. His detention had lasted nearly three months, beginning with his arrest on March 30.
Reuters reported the release that day. Indiana Public Radio covered the court order. According to Wisconsin Public Radio, Sarsour's attorneys reported he lost 30 pounds during detention. Supporters argued he was targeted for publicly criticizing Israel; ICE has not responded to that claim. The agency's official position—stated in its FY2024 annual report—is that detention is non-punitive and that noncitizens are held only when law or circumstances require it.
A Pattern Taking Shape
Sarsour's release is one in a series of court-ordered releases of Palestinians and pro-Palestinian activists from immigration detention in the United States.
Mahmoud Khalil, a Columbia University graduate and one of the highest-profile cases, was released from a Louisiana detention facility on June 20, 2025, after 104 days in federal custody, following a district court order. Reuters and AP reported the release the same day. The Third Circuit had ruled in January 2026 that Khalil should be freed by June 20, and the district court enforced that decision.
Other cases followed a similar pattern. Columbia student Mohsen Mahdawi was released from immigration custody on April 30, 2025, after a judge determined he was entitled to bail. Leqaa Kordia, a Palestinian from the West Bank arrested by ICE for overstaying an F-1 student visa, was released on a $100,000 bond on March 17, 2026, after Immigration Judge Tara Naselow-Nahas ordered it.
Each case moved through the same sequence: detention by immigration authorities, legal challenge, and a court order directing release. The legal arguments varied—habeas corpus (a legal tool used to challenge unlawful detention), bond hearings, bail determinations—but the broader pattern remained consistent. A Second Circuit ruling in April 2026 reinforced that district courts retain the power to order bond hearings and direct release when detention lacks legal foundation.
This pattern is not incidental. Multiple federal judges across different circuit courts have issued orders compelling release or bail hearings in this wave of enforcement actions. Yet none of these rulings has yet settled the larger constitutional question: whether the government may legally detain or deport a noncitizen based on protected political speech, and under what circumstances. That question is still being litigated.
Why Status Matters—and What Remains Unsettled
What distinguishes Sarsour's case from Khalil's or Mahdawi's is his legal standing. Khalil and Mahdawi were students on visas; their detention hinged partly on whether speech-related grounds could justify removal. Sarsour holds a green card—he is a legal permanent resident. This status carries legal weight that visa holders do not. Permanent residents face a higher bar for removal and receive stronger due process protections than nonimmigrant visa holders.
ICE has not publicly disclosed the specific reason for Sarsour's arrest or the legal grounds for his detention. His supporters, citing PBS NewsHour, argue his detention was retaliation for his speech. Whether a removal proceeding remains pending is unclear from public reporting.
The institutional significance of this pattern is worth noting. Courts have repeatedly intervened to question the legality of these detentions. The underlying constitutional question—whether protected political speech can be grounds for detention or deportation of a noncitizen—has not yet been resolved by any appellate court. Immigration law practitioners now have a growing body of district-level decisions addressing judicial review of permanent resident detention. For observers of national security and foreign policy, these cases reveal a tension: the administration has used immigration enforcement as a tool of foreign policy, while federal judges have repeatedly required it to justify individual detention decisions.
This tension has not been resolved. If anything, it has become clearer.
