Mahmoud Khalil, a legal permanent resident and Columbia alumnus, has garnered national attention after being detained by authorities for his involvement in pro-Palestinian protests at his former university last year. This case raises significant questions about free speech and the First Amendment as advocates express concern over the implications of his detention. The previous administration contends they possess the authority to deport Khalil without any criminal charges. This situation not only affects Khalil but poses broader implications for civil liberties across the country.
