Can anyone explain why Mahmoud Khalil deserves to have his green card revoked and be deported?

I don’t want to hear any false claims or claiming that he’s a terrorist because that will just make you look stupid. If you are unable to come up with a valid reason why he deserves this treatment then maybe you should rethink what you are really supporting.
