Federal authorities scrutinized approximately 5,000 student demonstrators whose names appeared on a public disclosure platform. According to an official account.
The ongoing lawsuit challenging the administration's deportation of pro-Palestinian scholars has shed light on a significant government operation targeting student protesters on U.S. college campuses. According to recent revelations, a special team known as the Tiger Team was established to investigate more than 5,000 individuals, primarily those named on a doxxing website that lists critics of Israel.
The Tiger Team's investigation followed a three-step process. The Office of Intelligence would provide reports of analysis to the National Security Division, which would then summarise the findings in a letter to the State Department. The State Department would make its determination and could take action accordingly.
Homeland Security Investigations (HSI) was responsible for producing between 100 to 200 reports of analysis on student protesters since it began its investigation. HSI's focus was on determining whether any of the protesters were violent or incited violence, or if they supported terrorist organizations.
However, it's important to note that HSI did not consider Canary Mission, a website often used as a source, as an authoritative one. The Tiger Team also examined students named on the Betar website, another Zionist website, in addition to Canary Mission.
The assistant director for the Office of Investigations within the Department of Homeland Security testified that analysts from various units were moved to work on the Tiger Team due to the large workload. He also stated that he had never seen this process used since 2019.
The efforts to crack down on pro-Palestinian protesters have led to at least several hundred visa revocations. As of early April 2025, at least 419 student and recent alumni visas have been revoked across more than 80 U.S. higher education institutions due to alleged pro-Hamas or related activities on social media and other platforms.
Additional reports suggest that hundreds, if not thousands, of international students have had their visas revoked nationwide as part of broader immigration enforcement efforts under this administration, particularly those whose political speech is supportive of Palestinian rights.
This intensified after a March 25, 2025 directive from the State Department, which made visa applicants ineligible if their social media showed support or sympathy towards terrorist organizations, with existing visas subject to revocation under similar criteria. The Department of Homeland Security also began screening social media for what it considers antisemitic content in April 2025.
The assistant director further testified that he was not given a deadline but knew that the work needed to be done expeditiously. Taking "months" to review the names on Canary Mission's list was not acceptable, according to him.
This marks the first time a government official has detailed how far the government has gone in its efforts to crack down on pro-Palestinian protesters. The lawsuit was filed by the American Association of University Professors and the Middle East Studies Association. The Tiger Team was created as a result of a March 2025 meeting of senior officials with Homeland Security Investigations.
The ongoing lawsuit and the revelations about the Tiger Team's activities are expected to continue, with the assistant director scheduled to return to the stand on Thursday.
- The recent revelations about the Tiger Team's activities have brought to light a significant international politics issue, as the investigation targeted more than 5,000 individuals, primarily students with pro-Palestinian views.
- The ongoing lawsuit, filed by the American Association of University Professors and the Middle East Studies Association, is shedding light on general news related to education-and-self-development and international affairs, as it challenges the administration's actions in revoking visas of pro-Palestinian scholars.
- The crackdown on pro-Palestinian protesters has not been limited to visa revocations, but also includes an analysis of social media content, with hundreds, if not thousands, of international students having their visas revoked nationwide. This issue raises concerns about freedom of speech and crime-and-justice implications.
