Detained anti-Israel protester Mahmoud Khalil filed suit Thursday to block Columbia University and Barnard College from turning over disciplinary records to Congress — claiming it would put student demonstrators at risk of “doxxing.”

Khalil – a Columbia grad who was arrested by ICE over the weekend – is suing the two affiliated schools and the House Committee on Education and Workforce after Chair Tim Walberg (R-Mich.) last month demanded the universities divulge information about students allegedly involved in “pervasive antisemitism.”

The suit claims that turning over the “confidential information” of students would violate their First Amendment right to free speech by exposing them to negative publicity and forcing the institutions to punish them.

“The Committee’s attempt to force the Universities to chastise and intimidate student organizers for protected speech is an abuse of its investigative powers,” the Manhattan federal court filing charges.

Khalil brought the new case alongside seven anonymous students — all of whom claim they were harmed when Columbia provided their records to the committee.

Further releases of student records “will undoubtedly cause irreparable reputational harm, as well as expose the University’s students to reprisals, harassment, doxxing, and perhaps even physical harm,” the court papers allege.

In what the filing dubs an act of “overreach,” the committee asked for records tied to 11 events “which likely involves the records of hundreds of students,” the suit claims.

For example, the committee wants information about the demonstrations at the Ivy League school from April, which culminated in students occupying Hamilton Hall, leading to classes being canceled and a rabbi warning Jewish students to stay away from campus amid the “extreme antisemitism.”  

The students in the lawsuit claim they all oppose antisemitism and support it being “confronted.” 

But the committee is launching “accusations of antisemitism to attack ideas it ideologically opposes,” exposing its “deep Islamophobia,” the filing claims.

Congress and the Trump administration are promoting a “new wave of repression” that poses “a great threat to the First Amendment, akin to the threat that McCarthyism” posed 50 years ago during the Cold War, the suit alleges.

The students are seeking unspecified damages for the alleged harm done to them due to the information that has already been released.

They also want a judge to issue a permanent injunction to bar Congress from forcing the schools to comply with the committee’s demands.

Khalil — a Palestinian descendant who lived in Syria — brought a separate petition earlier this week seeking to be released from ICE custody after the feds arrested him on the grounds he posed a risk to national security. 

The feds are seeking to deport Khalil, a green card holder who is married to an American who is eight months pregnant with his child. 

He’s currently being held in a Louisiana lock-up while he fights his case.

His arrest has sparked massive protests in New York, including on Thursday, when a mob of dozens flooded Trump Tower to push for Khalil to be freed, before cops began arresting the agitators.

Walberg said Thursday’s suit, “changes nothing.”

“The information the Committee is requesting is critical to its consideration of legislation on this issue,” the Republican chairman said. “Our Committee will continue its work to protect Jewish students and hold schools accountable for their failures to address rampant antisemitism on our college campuses.”

Columbia said it doesn’t comment on pending litigation. 

Barnard didn’t return a request for comment.
