Mahmoud Khalil, a Columbia University graduate and former student detained by ICE, sued the federal government for records about its use of doxing databases such as Canary Mission to identify pro-Palestinian protesters, according to the Center for Constitutional Rights. Khalil said an ICE official acknowledged using such sites during a deportation trial and that his earlier FOIA requests for related records have gone unanswered. The suit asks for transparency about government partnerships with private monitoring sites used to target student activists. Adina Marx-Arpadi, Khalil’s attorney, framed the case as seeking to reveal the depth of coordination between federal agencies and groups that compile dossiers on protesters; civil liberties groups warn the practice could chill campus speech and endanger students.
