On March 8, 2025, Immigration and Customs Enforcement (ICE) entered a Columbia University dormitory and abducted Palestinian activist Mahmoud Khalil. Mahmoud was a recent graduate of Columbia, a legal permanent resident, a husband, a soon-to-be father, and, ultimately, a detainee. In his 104 days in custody, he missed the birth and first two months of his son’s life.

Weeks after Mahmoud’s detention, Mohsen Mahdawi, another Palestinian Columbia student activist, traveled to a scheduled immigration appointment, a final step in his green card process, only to find ICE waiting for him. Mahmoud and Mohsen successfully challenged their deportations in federal court, but now, more than a year after their initial detentions, both activists face a renewed effort by the Trump administration to force their deportations.

The government has not alleged that Mahmoud or Mohsen committed crimes, violated the terms of their visas, or posed any actual security threat. It has, in its filings and public statements, cited their political activity in the form of their speech, their affiliations, and their presence at demonstrations against Israel’s genocide in Gaza. Visa revocation and deportation proceedings operate largely outside the scope of the procedural protections that constrain criminal prosecution. No legitimate due process is afforded in these instances; the state does not need to prove that an individual did something wrong, it just needs to show, with considerable latitude, that your presence is contrary to “national interests,” a justification that is deliberately ambiguous enough to label the protest of a genocide as “anti-American.”
