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.

The Alien Enemies Act of 1798 gives the president wartime powers to deport undocumented immigrants with little to no due process.

President Donald Trump on Friday downplayed his involvement in invoking the Alien Enemies Act of 1798 to deport Venezuelan migrants, saying for the first time that he hadn’t signed the proclamation, even as he stood by his administration’s move.
