Trump takes Venezuelan deportation case to Supreme Court

• Acting Solicitor General Sarah M. Harris argued that the lower court overstepped by barring the administration from deporting alleged gang members "engaged in a campaign of terror, murder, and kidnapping, aimed at destabilizing our country."

The latest: U.S. District Judge James Boasberg later on Friday extended until April 12 his temporary restraining order blocking the deportations, which were set to expire Saturday.

Context: The Trump administration this month defied Boasberg's court order barring the deportation of about 250 people the government claims are Tren de Aragua gang members.

• The seldom used Aliens Enemies Act of 1798 gives the executive branch extreme power to deport noncitizens without a judicial hearing during times of war.

What they're saying: "This case presents fundamental questions about who decides how to conduct sensitive national-security-related operations in this country — the President, through Article II, or the Judiciary, through [temporary restraining orders," Harris wrote.

• She also said halting the deportations threatens "the government's sensitive negotiations with foreign powers."
