Mahmoud Khalil vowed to resume his pro-Palestinian activism as he returned to New York a day after he was released on bail from a jail for immigrants, even as U.S. President Donald Trump's administration said it will continue its efforts to deport the recent Columbia University graduate.

Former Columbia University student Mahmoud Khalil has returned to the U.S. Northeast after 104 days in custody for protesting against Israel and the war in Gaza.

Mahmoud Khalil is back in New Jersey after a federal judge ordered his release from U.S. Immigration and Customs Enforcement detention in Louisiana. The Columbia University graduate and activist arrived on a flight to Newark Liberty International Airport on Saturday after spending months in ICE custody as the Trump administration fights to deport him.
