Kilmar Abrego Garcia, the Alien Enemies Act, and a Test of US Migration Law

On 23 June 2026, the United States Department of Justice moved to revive criminal human-smuggling charges against Kilmar Abrego Garcia, a Salvadoran national whose name has become shorthand for a much larger argument about the reach of presidential migration power. The appeal, filed against a March 2025 dismissal, is a procedural step rather than a constitutional ruling, but it lands at a moment when every thread of the case — the Alien Enemies Act invocation, the swift removal to El Salvador's CECOT mega-prison, the fight over whether a third-country national can be sent to a country he has never lived in — is being relitigated in courtrooms from Greenbelt, Maryland to the Fourth Circuit in Richmond.

The filing matters because Abrego Garcia is no longer an isolated defendant. He is the test case for a theory of executive power that treats membership in a designated foreign gang as a basis for removal to a third country, with limited federal-court review of the underlying removal order. If DOJ can re-establish the smuggling count and tether the deportation litigation to a domestic criminal case, the Department gives itself a second, criminal-law handle on a defendant who has already won the most significant immigration ruling of the year.

The factual spine is well established. Abrego Garcia entered the United States as a teenager, was detained by US Immigration and Customs Enforcement in 2019, and was issued a final order of removal — but to El Salvador, not to any country he had previously lived in. In March 2025, the Trump administration invoked the Alien Enemies Act, a 1798 wartime statute dormant since World War II, to justify expedited removals of alleged Tren de Aragua members. Abrego Garcia was placed on a removal flight to El Salvador and sent to the CECOT facility operated by President Nayib Bukele's government. A federal judge later found the removal was a clear error and ordered his return; the administration produced no record showing he was, in fact, a member of Tren de Aragua.

The criminal case underneath the immigration case

What the 23 June appeal actually targets is a narrower piece of the file. In 2024, a grand jury in the Middle District of Maryland indicted Abrego Garcia on charges of human smuggling — specifically, allegations that he transported undocumented migrants within the United States in exchange for payment. The indictment was the product of a multi-agency investigation that included a confidential informant and recorded text messages the government contends document the alleged activity. Defense counsel has framed those messages as innocuous.

In March 2025, the district court dismissed the indictment. The grounds for dismissal are the focus of the government's appeal. A ruling on the merits would be the first time a federal appellate court weighs in on whether the smuggling statute reaches the conduct alleged, on whether the 1798 wartime removal framework is properly applied to a person who lacks any documented affiliation with a designated foreign organisation, and on whether a criminal indictment can proceed against a defendant who has already been removed under immigration authority. The government argues yes on each count. The defense argues that the underlying removal was unlawful, that the criminal case is being repurposed to dress up a failed immigration proceeding, and that the court should defer to the suppression remedies available in the immigration context.

The second front in the case is a civil suit the ACLU and its partners have pursued on Abrego Garcia's behalf since mid-2025. That litigation has produced the most legally consequential ruling to date: a finding that the administration's invocation of the Alien Enemies Act against a non-member of a designated gang, with no advance notice of removal, exceeded statutory authority. That order is now on appeal to the Fourth Circuit. The criminal case the DOJ is trying to resurrect is, functionally, the Department's backup plan — a parallel track that, if successful, would land Abrego Garcia in federal prison rather than the procedural limbo of an unexecuted removal order.

The Aliens Enemies Act, CECOT, and the question of a third country

The legal architecture is older than the country. The Alien Enemies Act of 1798 authorises the President, in time of declared war or a presidentially characterised "invasion or predatory incursion," to detain or remove nationals of a hostile foreign power. It was last used during the Second World War. The Trump administration's 2025 invocation extended the statute to members of Tren de Aragua, a Venezuelan transnational gang that the State Department had earlier designated a foreign terrorist organisation.

The extension is the heart of the constitutional argument. Critics note that the statute is keyed to the conduct of a foreign state, not a non-state criminal organisation, and that a gang designation does not amount to an "invasion." The administration's brief in the parallel civil litigation argues that the predicate is satisfied by what it characterises as an organised, cross-border criminal presence. The judge who ordered Abrego Garcia's return rejected the broader theory without reaching the constitutional question; the Fourth Circuit will have to.

A separate line of argument concerns the destination country. El Salvador is not Abrego Garcia's country of origin, citizenship, or any documented residence. The administration's position is that the government may remove a non-citizen to a third country with which the United States has an arrangement for custody, regardless of the individual's prior presence there. Critics counter that the immigration statute contemplates removal to the country of origin unless a specific agreement provides otherwise, and that the arrangement with the Bukele government — the CECOT detention contract concluded in 2025 — does not satisfy the statute's textual requirements. The Salvadoran government has not publicly contested the arrangement; the disagreement is between the US executive and US federal courts.

What the wire is covering — and what it is not

Coverage of the case in US outlets has split along familiar lines. Establishment reporting has tracked the litigation through the courts and quoted legal academics on the broader implications. The administration's communications team has framed Abrego Garcia as a member of MS-13 in 2019 reporting and, more recently, as a Tren de Aragua operative — characterisations that the court record does not support, and that the government has retreated from in open filings. A smaller group of outlets has treated the case as a deliverable: a story that produces clicks when paired with a specific gang label, regardless of the evidentiary record.

What the wire coverage has under-played is the structural issue. The criminal prosecution the DOJ is now appealing was, by the government's own timetable, a marginal matter until the immigration case broke open. The decision to push it forward, and to do so on appeal, is best read as a strategic choice to give the Department two ways to win: a reinstated criminal conviction, or a reinstated civil removal authority, on the same set of facts. Each track strengthens the other. A conviction would moot many of the suppression arguments in the civil case; a successful civil appeal would moot the defendant's standing to challenge criminal discovery.

The Salvadoran dimension of the case has drawn less attention than the constitutional questions, and the omission is consequential. The CECOT arrangement is the only material reason the United States is in a position to send a Salvadoran national to El Salvador without the country's cooperation under a normal removal order. That arrangement — a prisoner-diplomacy contract negotiated between the Trump administration and the Bukele government in 2025 — is its own subject of public-interest litigation, and its legality is not settled. If the contract is held to be invalid, the basis for any third-country removal under the Alien Enemies Act in this case collapses.

Stakes and forward view

If DOJ prevails on appeal, the case returns to the district court for trial and the government's parallel civil litigation becomes harder to manage for the defense. If the defense prevails, the government is back to square one on the smuggling count and faces a harder row to hoe in the Fourth Circuit. The civil case, in either outcome, is now the more significant of the two for the country as a whole, because the constitutional question — whether a non-state gang designation can activate a wartime removal statute in the absence of a foreign-state conflict — will eventually be decided there.

The time horizon is measured in months, not weeks. The Fourth Circuit is unlikely to resolve the broader question before the end of 2026, and a Supreme Court appeal is a realistic possibility on either side. By the time the litigation concludes, the administration will have shown whether the use of a centuries-old wartime statute to remove a non-state-organisation member, with no prior connection to the destination country, was a one-off or a template. The Abrego Garcia case is, in that sense, the leading indicator. A win for the government on either track ratifies the template; a loss narrows it.

The most uncertain element is the least discussed: what the United States will do if a federal court orders the government to bring Abrego Garcia back from El Salvador, and the Bukele administration declines to release him. The current record shows the administration has produced no evidence of effective authority over the CECOT population. The same uncertainty sits on the criminal side. If the criminal indictment is reinstated and the defendant remains in Salvadoran custody, the court's authority to compel appearance is in question. The administration has not, in public filings, addressed how that gap would be closed.

The staff writer framed this case around the appellate posture and the underlying statutory questions, rather than the gang-labelling language that has dominated political coverage. The legal record — not the communications operation — is the story.
