The Trump administration has submitted a brief to deport Mahmoud Khalil, a former student at Columbia University who organized anti-Israel protests on campus, citing foreign policy grounds. The government argues that Khalil's presence undermines efforts to combat antisemitism and protect Jewish communities. Khalil, who denies accusations of antisemitism, was apprehended by immigration officers in March and is currently detained in Louisiana. Attorneys representing Khalil criticize the filing as an attack on constitutionally protected expression.
