Federal agents arrest Palestinian activist Mahmoud Khalil

Federal agents arrested Mahmoud Khalil, a Palestinian activist and Columbia University graduate student, in a video released on Friday. The arrest occurred in his apartment building lobby, alarming free-speech advocates. Khalil, a lawful U.S. resident, was handcuffed while assuring his pregnant wife he would be fine. The Justice Department is investigating whether Columbia University concealed illegal immigrants. Khalil's visa was revoked due to his involvement in pro-Palestinian protests, which officials claim incited anti-Jewish sentiment. His lawyers are challenging his detention in court. Khalil was transferred to a detention center in Louisiana after his arrest. He expressed concern about missing the birth of his first child and the impact on his ability to advocate for Palestinian rights.
