The Supreme Court blocked the Trump administration from deporting a second wave of Venezuelan immigrants under the Alien Enemies Act after lawyers rushed to the court and alleged that the administration was about to send dozens or hundreds of detainees to El Salvador in defiance of an earlier ruling by the justices.

President Donald Trump’s administration asked the Supreme Court to roll back its decision to block the deportation of Venezuelans to a notorious prison in El Salvador, arguing that the early-morning order was overbroad and premature.

The Supreme Court blocked, for now, the deportation of a group of Venezuelan migrants whom the Trump administration is seeking to remove under a rarely used wartime law.The order came early Saturday after lawyers for the migrants asked the justices to step in on an emergency basis to halt their deportations as reports came that immigration officials began loading the detainees onto buses for deportation under the Alien Enemies Act.
