A federal judge says the Trump administration can continue to detain Columbia University protester Mahmoud Khalil on allegations that he lied on his green card application.

A judge says the Trump administration can detain Columbia activist Mahmoud Khalil for allegedly lying on his green card application — after ruling he can't be jailed for foreign policy reasons.

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.
