Columbia University student Mahmoud Khalil remains in jail in Louisiana as a US judge considers whether his challenge should be heard there or in New Jersey. The Trump administration defends Khalil's arrest and deportation efforts against pro-Palestinian activists. Khalil's lawyers argue that he was targeted for his political views and should be released to be with his wife for the birth of their child. The government accuses Khalil of not disclosing his involvement with UNRWA and his employment at the British embassy in Beirut.
