As the Trump administration identified pro-Palestinian academics to target for deportation, it relied heavily on an anonymously-run pro-Israel website that has been criticized for doxxing, according to newly unsealed court documents and testimony at an ongoing trial.

To support President Donald Trump’s deportation drive, the Department of Homeland Security assembled a “tiger team” of intelligence analysts who built dossiers on about 100 foreign students and scholars engaged in pro-Palestinian activity, the records show.

More than 75 of those people were identified by the shadowy website Canary Mission, according to deposition testimony unveiled this week in a case challenging the Trump administration’s targeting of pro-Palestinian scholars.

The federal judge currently overseeing a trial in the case unsealed the deposition transcripts, which contain hundreds of pages of sworn testimony by administration officials about the campus deportation effort. Some of the details in the transcripts were fleshed out in open court Wednesday as administration officials began to be called to the witness stand.

In response to a query from POLITICO, Canary Mission said in a statement Wednesday that it “had no contact with this administration or the previous administration.”

The unsealed court records also reveal for the first time how deeply involved the Trump White House — in particular top Trump aide Stephen Miller — was in the effort to revoke the visas of pro-Palestinian academics studying and teaching at American colleges.

The acting chief of the State Department’s Bureau of Consular Affairs, John Armstrong, testified that he’d had “at least a dozen” conversations with White House officials about the student deportation drive and that Miller was on interagency conference calls related to the issue “at one point at least weekly.”

According to Armstrong, the conference calls with Miller lasted about 15 minutes to an hour and involved other officials from the Homeland Security Council, the State Department and Homeland Security Department.

The extent of the White House’s involvement in singling out particular students remains unclear because the White House asserted executive privilege to conceal the details of Miller’s exchanges with agency officials.

Still, the revelations shed new light on the Trump administration’s aggressive efforts to target, detain and deport foreign academics who are living and working in the country legally. For months, Secretary of State Marco Rubio appeared to be the face of those efforts: He invoked a rarely used provision of immigration law to try to deport targeted scholars — including Mahmoud Khalil and Rumesya Ozturk — by declaring their presence in the U.S. in conflict with American foreign policy interests.
