Immigration attorneys are scrambling to seek emergency relief from a federal court in Texas after learning that Venezuelan migrants detained there received notices that they are subject to President Donald Trump’s Alien Enemies Act proclamation issued last month.

The American Civil Liberties Union asked a federal judge to issue a temporary restraining order preventing officials from using the Alien Enemies Act to deport Venezuelan men held at an immigration detention center in Texas.

A Texas judge blocked deportations of anyone held in a south Texas detention facility who may be removed under the wartime law, and a New York judge planned a similar order.
