The immediate backdrop is the broader national-security and immigration enforcement environment during an active U.S.-Israel military campaign against Iran that began with coordinated strikes in March 2026; those strikes prompted tightened homeland security postures and stepped-up immigration reviews across U.S. agencies in the months that followed.
Structurally, U.S. deportation authority rests on the Immigration and Nationality Act (INA, enacted 1952, amended repeatedly), the Illegal Immigration Reform and Immigrant Responsibility Act of September 30, 1996, and the Department of Homeland Security created by the Homeland Security Act of November 25, 2002, which centralized removal and immigration-enforcement powers.
Mahmoud Khalil has filed a new lawsuit accusing Columbia University and the dean of his master's program of failing to protect him and other protestors from discrimination and harassment, the New York Post reports.
The paper presents Khalil as an Algerian national who has repeatedly confronted Columbia administrators and law enforcement through what it calls unlawful demonstrations tied to a group the story names Columbia University Apartheid Divest.
The suit comes as, the Post says, Khalil faces imminent deportation; the article treats his legal filings as part of a broader campaign of litigation and public protest.
The Post notes Khalil previously sued Columbia and several federal lawmakers in March 2025 and, it reports, brought separate suits in July 2026 against government officials, think tanks and nonprofits he says conspired to oust him.
Columbia University and the dean named in the Post excerpt did not provide statements in the quoted text; the story emphasizes Khalil's activism and legal strategy rather than the university's response.
This filing adds to a pattern, at least as the Post frames it, of Khalil using litigation alongside campus protest to contest actions he says threaten him; the paper characterizes his activity as central to the immigration risk he now faces.
Confirmed in the article are Khalil's nationality, the parties he sued, the claim that the university failed to protect protestors from harassment, and the existence of prior related lawsuits; the Post supplies character judgment about the demonstrations that other outlets might not echo.
The immediate practical question raised by the filing is whether courts will treat these allegations as bearing on Khalil's immigration case; the available reporting in this source does not document any legal rulings tied to the new suit or Columbia's formal defense, leaving the outcome and timetable unresolved.
