Khalil challenges deportation, claims retaliatory detention

Mahmoud Khalil, a Columbia University graduate student, has filed an amended complaint naming President Donald Trump and Secretary of State Marco Rubio. Khalil is challenging his attempted deportation after being detained for participating in protests against the Gaza war. Khalil's lawyers argue that his detention is retaliatory and violates his free speech rights. He was arrested by immigration authorities in New York and is currently facing deportation under a foreign-policy clause in immigration law. A federal judge has temporarily blocked Khalil's deportation while the case is reviewed. The Department of Homeland Security claims Khalil's activities align with Hamas, while advocates argue he is being punished for lawful protests.
