A judge will hear arguments Thursday over whether the Trump administration defied a court order when they deported alleged migrant gang members to El Salvador.

A federal appeals court issued a decision in a high-profile immigration case challenging the Trump administration's authority to deport Venezuelan nationals via a 1798 wartime law.

U.S. District Court Judge James Boasberg won’t lift his earlier ban on the deportation of immigrants under the Alien Enemies Act, denying a Trump administration request and ruling it likely violated the due process rights of migrants who were deported to El Salvador.
