The US Department of Homeland Security (DHS) confirmed the arrest of Khalil, a recent Columbia graduate who has worked for the British embassy in Beirut, and  that Khalil’s activism constituted “activities aligned to Hamas”.

A Columbia spokesperson told the Associated Press over the weekend that law enforcement officials needed a warrant to enter university property but did not disclose whether the school had received a warrant for Khalil’s arrest.

The university recently issued guidance on “potential visits to campus” by Ice, where it states that  “university buildings or people without a warrant”.

Khalil’s detention has sparked outrage from civil rights groups and first amendment organizations and advocates.

Jameel Jaffer, executive director at the Knight First Amendment Institute at Columbia University,  that “arresting and threatening to deport students because of their participation in political protest is the kind of action one ordinarily associates with the world’s most repressive regimes”.

He said that universities “must recognize that these actions pose an existential threat to academic life itself” and “make clear, through action, that they will not sit on the sidelines as the  terrorizes students and faculty alike and runs roughshod over individual rights and the rule of law”.

Donna Lieberman, executive director of the New York Civil Liberties Union,  Khalil’s detention as a “targeted, retaliatory, and an extreme attack on his first amendment rights”.

“The unlawful detention of Mr Khalil reeks of McCarthyism,” Lieberman said. “It’s clear that the Trump administration is selectively punishing Mr Khalil for expressing views that aren’t Maga-approved – which is a frightening escalation of Trump’s crackdown on pro-Palestine speech, and an aggressive abuse of immigration law.”

Lieberman warned that “ripping a student from their home, challenging their immigration status, and detaining them solely based on political viewpoint will chill student speech and advocacy across campus” and said that “political speech should never be a basis of punishment, or lead to deportation”.

The Foundation for Individual Rights and Expression (Fire)  that “anyone facing arrest and detention must be afforded due process” stating that just as students and demonstrators “are obliged to abide by lawful rules of conduct, our government must abide by the first amendment”.

“The government must be clear and transparent about the basis for its actions to avoid chilling protected speech,” the statement added.

Mukherjee said that if the government were to revoke Khalil’s green card “in retaliation for his public speech, that is prohibited by the first amendment of the US constitution”.

Eli Northrup, a New York City public defender and policy advocate,  on social media that “no matter what your views are on Israel & Palestine, you should be terrified of a country incarcerating its residents for exercising free speech.”

Murad Awawdeh, president of the New York Immigration Coalition, said in a  “Khalil and all people living in the United States are afforded due process.

“A green card can only be revoked by an immigration judge, showing once again that the Trump administration is willing to ignore the law in order to instill fear and further its racist agenda” Awawdeh said.

Several New York City , leaders and advocates also  Khalil’s arrest and called for his release.

Zohran Mamdani, the Queens assembly member and , called the arrest “a blatant assault on the first amendment and a sign of advancing authoritarianism under Trump”.

The New York City comptroller, Brad Lander,  described the arrest as unconstitutional, and argued that deporting individuals for their speech does not make any community safer.

“I disagree strongly with things that were said in the protests he reportedly led. But it will not make Jews – or any of us – safer for the federal government to deport people for saying things we may find hateful.”

The student workers union at Columbia University  Columbia university leadership to protect their international students. “By allowing Ice on campus, Columbia is surrendering to the Trump administration’s assault on universities across the country and sacrificing international students to protect its finances,” the union said.

“The Trump admin is going after students who have used their first amendment, constitutional rights,” Jayapal wrote. “Deporting legal residents solely for expressing their political opinions is a violation of free speech rights. Who’s next? Citizens?”

While first amendment groups have condemned the arrest, the Columbia Jewish Alumni Association  on social media on Sunday,  it “exactly what needs to happen to restore order to campuses like Columbia and our country”.

The Anti-Defamation League (ADL), a group that  as fighting antisemitism and all forms of hate, also  that they “appreciate the Trump administration’s broad, bold set of efforts to counter campus antisemitism” and said that Khalil’s arrest “further illustrates that resolve by holding alleged perpetrators responsible for their actions”.

But the group emphasized that any deportation, revocation of a green card or visa “must be undertaken in alignment with required due process protection”.

One of the groups  was Jewish Voice for Peace, who describe themselves as the “largest progressive Jewish anti-Zionist organization in the world”.

On Monday, Jonah Rubin, the senior manager of campus organizing for JVP said that that Khalil’s arrest was designed to instill terror “throughout immigrant communities and social justice movements on college campuses”.

“Even as we work to free Mahmoud Khalil, Columbia and every other college and university must stop complying with the illegal and unconstitutional orders of the Trump regime, and must start taking active measures to protect their students,” Rubin said.

Before his arrest, Khalil had told  that he feared that he would be targeted by the federal government.
