A federal judge has warned the Trump administration -- amid reports it plans to deport migrants to Libya -- that doing so would violate court orders prohibiting the government from shipping deportees to a third country.

A U.S. judge said any effort by the Trump administration to deport migrants to Libya would clearly violate a prior court order barring officials from swiftly deporting migrants to countries other than their own without first weighing whether they risk persecution or torture if sent there.

The Trump administration is moving forward with plans to transport a group of undocumented immigrants to Libya on a US military plane, an administration official told CNN.
