The student in question participated in a protest in support of Palestinians, not Hamas. There is no evidence presented they provided material support to Hamas, and there is no evidence they provided verbal support of Hamas. So yes, it's controversial that a student, participating in a student protest, protesting a war, was deported without due process. And this is before we mention the government has admitted, in court document, that they illegally deported a visa holder to El Salvador, and "oops" since he's already in a prison overseas there's nothing our court system can do about it. So yes, controversies abound with the way this administration is "enforcing" immigration law.
