A federal judge has ruled that the government cannot deport and must release Mahmoud Khalil, the student whom the Trump administration jailed over his participation in pro-Palestinian demonstrations at Columbia University.

Khalil has been detained since he was arrested in March. The government has argued that the secretary of state can “personally determine” whether he should remain in the country.

Mahmoud Khalil’s hopes of being freed on bond as he continues fighting the Trump administration’s efforts to deport him were dashed Friday, despite a judge saying the government could no longer hold Khalil on the premise that his presence in the country is against the national interest.
