Mahmoud Khalil was denied release on Friday by a judge who, earlier in the week, had rejected the Trump administration’s main legal basis for seeking to deport and detain the pro-Palestinian activist.

A federal judge on Friday determined that Mahmoud Khalil, the pro-Palestinian activist from Columbia University, will remain in Immigration and Customs Enforcement (ICE) detention after the federal government pivoted its legal strategy.

A federal judge ruled this week that the government could not continue to hold the Columbia University graduate under the rarely invoked law it originally used to detain him.
