A federal court petition demanding Mahmoud Khalil’s release provides details of the Columbia University activist’s arrest. Trump says more arrests are to come.

A federal judge has halted the deportation of a Columbia University graduate student who was detained by immigration authorities for his participation in campus protests over the Israel-Hamas war. Judge Jesse Furman of the Southern District of New York issued the order Monday as the government sought to deport Mahmoud Khalil after arresting him outside his apartment over the weekend.

U.S. President Donald Trump said on Monday that the arrest of a Palestinian graduate student who has played a prominent role in pro-Palestinian protests at New York's Columbia University will be followed by others.
