President Donald Trump was furious after the Supreme Court left in place a lower court ruling that prevents him from using the Alien Enemies Act to deport members of a Venezuelan gang, Tren de Aragua.

“The Supreme Court has ruled that the worst murderers, drug dealers, gang members, and even those who are mentally insane, who came into our Country illegally, are not allowed to be forced out without going through a long, protracted, and expensive Legal Process, one that will take, possibly, many years for each person, and one that will allow these people to commit many crimes before they even see the inside of a Courthouse,” he said on Truth Social. “The result of this decision will let more CRIMINALS pour into our Country, doing great harm to our cherished American public.”

“It will also encourage other criminals to illegally enter our Country, wreaking havoc and bedlam wherever they go,” the president said.

“The Supreme Court of the United States is not allowing me to do what I was elected to do. Sleepy Joe Biden allowed MILLIONS of Criminal Aliens to come into our Country without any ‘PROCESS’ but, in order to get them out of Country, we have to go through a long and extended PROCESS,” he said.

The court said that the illegal aliens who were being deported were not given enough notice, but it did not rule on whether the president was allowed to use the Alien Enemies Act to deport them.

“Under these circumstances, notice roughly 24 hours before removal, devoid of information about how to exercise due process rights to contest that removal, surely does not pass muster,” the justices said in the decision.

“To be clear, we decide today only that the detainees are entitled to more notice than was given on April 18, and we grant temporary injunctive relief to preserve our jurisdiction while the question of what notice is due is adjudicated,” the court said.

“The Government may remove the named plaintiffs or putative class members under other lawful authorities,” it said.
