U.S. District Judge James Boasberg ordered a 14-day pause on all efforts to deport Venezuelan illegal immigrants under the Alien Enemies Act.

A federal judge temporarily blocked the Trump administration’s ability to use a sweeping wartime authority to quickly deport some migrants whom the US has accused of being affiliated with the Venezuelan gang Tren de Aragua.

The president had looked to the Alien Enemies Act, first passed in 1798, to help speed up the pace for removing migrants.
