The case raises questions about the Trump administration's adherence to limits set by the Supreme Court. It carries the risk of a significant clash between the two coequal branches of government and potentially a full-blown constitutional crisis.

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.
