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.

Justices Clarence Thomas and Samuel A. Alito Jr. dissented. A group of Venezuelan migrants had been scheduled to be flown out of the country under the little-used wartime statute, according to people familiar with the matter.

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.
