Mar 13: CU issued the following announcement: “Today, the Columbia University Judicial Board determined findings and issued sanctions to students ranging from multi-year suspensions, temporary degree revocations, and expulsions related to the occupation of Hamilton Hall last spring. With respect to other events taking place last spring, the UJB’s determinations recognized previously imposed disciplinary action. The return of suspended students will be overseen by Columbia’s University Life Office. Columbia is committed to enforcing the University’s Rules and Policies and improving our disciplinary processes.”

Mar 13: A letter to CU co-signed by the GSA, DoE, and HHS imposed several “preconditions for formal negotiations regarding CU’s continued financial relationship” with the feds, requiring “expulsion or multi-year suspension” for students who occupied Hamilton Hall, abolition of the University Judicial Board and “centraliz[ation of] all disciplinary processes under the Office of the President,”time, place, and manner” restrictions “to prevent disruption of teaching, research, and campus life,” a ban on all masks except those worn for religious or health reasons, restrictions and punishments for “unrecognized” groups, “promulgat[ion of] a definition of antisemitism including “Anti-‘Zionist’ discrimination against Jews in areas unrelated to Israel or Middle East,” giving CU security “full law enforcement authority,” placing the Middle East, South Asian, and African Studies department under academic receivership,” and a “comprehensive admissions reform.”

Mar 13: Interesting details about Elvin Hernandez, one of the ICE officers who arrested Kahlil — and was honored by name by Trump at the State of the Union in 2019

Mar 13: Columbia “expelled and fired Grant Miner, President of UAW Local 2710, which represents thousands of Columbia student workers. The firing comes one day before contract negotiations were set to open with the University.”

Mar 14: DHS released the following statement: “VIDEO: Columbia University Student Whose Visa Was Revoked for Supporting Hamas and Terrorist Activities Used CBP Home App to Self- Deport Release Date: March 14, 2025 Another student who supported Hamas was arrested by ICE HSI for overstaying her student visa. WASHINGTON - Today, Secretary of Homeland Security Kristi Noem announced that one of the Columbia students who had her student visa revoked for advocating for violence and terrorism self-deported using the CBP Home App and ICE arrested a Palestinian student for overstaying her expired F-1 visa. Ranjani Srinivasan, a citizen and national of India, entered the United States on a F-1 student visa as doctoral student in Urban Planning at Columbia University. Srinivasan was involved in activities supporting Hammas, a terrorist organization. On March 5, 2025, the Department of State revoked her visa. The Department of Homeland Security has obtained video footage of her using the CBP Home App to self-deport on March 11. Another student Leqaa Kordia, a Palestinian from West Bank, was arrested by ICE HSI Newark officers for overstaying her expired F-1 student visa. Her visa terminated on January 26, 2022, for lack of attendance. Previously, in April 2024 Kordia was arrested for her involvement in pro-Hamas protests at Columbia University in New York City. The below statement is attributable to Secretary Noem: “It is a privilege to be granted a visa to live and study in the United States of America. When you advocate for violence and terrorism that privilege should be revoked, and you should not be in this country. I am glad to see one of the Columbia University terrorist sympathizers use the CBP Home app to self-deport.”

Mar 14: The Guardian reports that Betar US, “a far-right group that claimed credit for the arrest of a Palestinian activist and permanent US resident who the Trump administration is seeking to deport claims it has submitted ‘thousands of names’ for similar treatment.” Events above strongly suggest that Kahlil’s arrest stemmed from a similar arrangement, i.e., Betar guiding Trump and ICE operatives at least.
