ICE arrests Palestinian activist who helped lead Columbia protests, lawyer says

Mahmoud Khalil, a Palestinian activist and former Columbia University student leader, was arrested by federal immigration authorities at his university-owned apartment. His attorney, Amy Greer, reported that the agents claimed to be acting on a state department order to revoke his green card, despite Khalil being a permanent resident. This arrest coincides with the Trump administration's intensified scrutiny of foreign students involved in protests against Israel's actions in Gaza. Khalil has been a prominent figure in the pro-Palestinian movement at Columbia, where he played a key role in student protests. The university has faced criticism from the government for not adequately addressing antisemitism on campus, leading to a significant cut in federal funding. Khalil's detention has raised concerns about the administration's approach to free speech and due process, as immigration courts are the only entities authorized to revoke green cards. His case is part of a broader investigation into students expressing pro-Palestinian sentiments, with many facing disciplinary actions for their activism. Khalil's wife, who is pregnant, has not been informed of the reasons for his detention. Advocates for Khalil argue that his arrest is a violation of constitutional rights and an attempt to suppress dissenting voices.

If you hold a green card and support an organization which has been deemed a terrorist organization by the US government, you are taking a giant risk and are quite likely to be deported (legally). Section 237 of INA explicitly calls it out.

Most green card holders will tell you they feel like a guest in the country. Getting involved in protests and supporting organizations on the terror list etc seems rather silly...

Supposedly they moved him to Louisiana after and in response to habeaus corpus being filed by his lawyers (https://bsky.app/profile/chrisgeidner.bsky.social/post/3lk2k...) which is, of course, incredibly alarming.

For those who aren't familiar, habeas corpus is an incredibly important civil right that effectively allows anyone who is detained to go to court to challenge the detention. Khalil's lawyers state that after they filed for habeas corpus, ICE moved Khalil to Lousiana without telling anyone. Extremely concerning.

>Last week it was reported by Axios that Secretary of State Marco Rubio intends to revoke visas from foreign nationals who are deemed to support Hamas or other terrorist groups, using artificial intelligence (AI) to pick out individuals [on social media]

Yikes. Once the government has built that infrastructure and pipeline from monitoring to arrest, you think they won't use it for other kinds of dissent?

How we can we help him get proper legal help and awareness on a regular basis? Is HN beyond sticky threads? Seems like society in general is, but ... we need sticky threads at this point.

My understanding of the relevant law and legal precedent is that since revoking a green card and deporting someone is not technically a criminal penalty, it may be constitutional for the government to so. Reno vs AADC went to SCOTUS in 1999, and that was roughly the ruling, although it's unclear how much of a precedent that sets, because the lower court's ruling was rejected due to lack of jurisdiction.

Even if that is considered settled (which, personally, I find a pretty lousy interpretation of the first amendment), it would still make this arrest and detention totally illegal, at least warranting a lawsuit, even if deportation can't be avoided.

Hopefully I'm wrong. This whole thing is so destructive to the constitution, to personal liberties, and to higher education.

> who claimed they were acting on a state department order to revoke his green card, according to his attorney

I thought green cards can only be revoked in rather limited circumstances. What is he accused of?

headline is misleading, as far as anyone can tell he's been kidnapped, not arrested. allegedly, they:

- follow him in to his home

- refuse to identify themselves

- tell him his green card has been cancelled

- tell his wife they'll kidnap her too if she intervenes

- takes him somewhere

- won't tell anyone where he is, including his (8 month pregnant) wife and lawyer

allegedly they have done this because he's been loudly critical of the policies of a foreign government, which as everyone knows, is not a crime. as everyone also knows, random feds can't just kidnap you even if they think you have committed an actual crime.

I don't think they believe they can revoke his green card and deport it. If they actually can then they'll do it but what they want are the headlines and the fear.

He has a green card, he is protected by the First Amendment.

It's not more complicated than that.
