WASHINGTON (TNND) — The Bluebonnet Detention Center in Anson, Texas, is just the latest backdrop in the debate over immigration.

Over the weekend, NBC News obtained video of an Immigration and Customs Enforcement bus filled with Venezuelan migrants reportedly headed to the airport.

The Trump Administration has insisted they were members of Tren de Aragua, which most of the men deny, instead asserting they were targeted for their tattoos.

The plan was to deport them, under the Alien Enemies Act, but after departing the detention facility for the airport, the bus can be seen abruptly returning.

That same night, the Supreme Court issued this order:

"The government is directed not to remove any member of the putative class of detainees from the United States until further order of this court."

While unsigned, it made clear, "Justice Thomas and Justice Alito dissent from the Court’s order. "

In a separate statement, Justice Samuel Alito wrote, wrote, "Literally in the middle of the night, the court issued unprecedented and legally questionable relief without giving the lower courts a chance to rule, without hearing from the opposing party, within eight hours of receiving the application, with dubious factual support for its order, and without providing any explanation for its order."

ICE officials, meanwhile, have been releasing names of those it's arrested and crimes associated with them.

That includes a Salvadoran national, convicted of sex offenses with a minor, and a Mexican national, who it says was convicted of attempted murder.

The Trump Administration, meanwhile, has been standing firm in its decision. President Donald Trump on Monday told reporters at the White House Easter Egg Roll:

We had millions and millions of people come in who are criminals, who are murderers, who are everything you can imagine. Drug lords, drug dealers. They came in from prisons and from mental institutions. And I was elected to move them out."

In an appearance on ABC's "This Week," White House Border Czar Tom Homan said, "I believe we're removing public safety threats and terrorists, designated terrorists, to that prison in El Salvador. Tren de Aragua, MS-13 are designated terrorist organizations," he said, adding, "We’re following the laws of this country and there's a different procedure for each one."

The law guaranteeing due process remains central to all of this.

Even an initial ruling from the Supreme Court said that anyone the government wants to deport under the Alien Enemies Act needs to be given the opportunity to first challenge that decision.

The legal battles over the Trump Administration’s use of the Alien Enemies Act are being fought at every level, including a split within the highest court in the land.
