On March 15, 2025, President Trump invoked the Alien Enemies Act of 1798 to authorize rapid deportation of Venezuelan nationals alleged to be members of the Tren de Aragua gang. The administration deported 238 individuals to El Salvador, with 137 removed under the Alien Enemies Act and 101 under regular immigration law. Judge James Boasberg issued a temporary restraining order blocking the deportations, but the administration proceeded with the flights. The deportees were held in El Salvador's CECOT maximum-security prison. The action sparked immediate legal challenges questioning whether a criminal gang qualifies as an enemy state under the 1798 law and whether the deportations violated due process rights.
The Alien Enemies Act, passed in 1798, grants presidents power to detain or deport noncitizens from countries deemed hostile during wartime or invasion. The law had only been invoked three times previously—during the War of 1812 and both World Wars—always during congressionally declared wars. Trump's 2025 invocation marked the first peacetime use and the first application to a criminal organization rather than a foreign nation-state. Legal experts and courts questioned whether the statute's plain language permitted such expansion beyond its historical wartime context.

Critics argued the Alien Enemies Act requires a declared war or actual foreign invasion, not gang activity, and that deporting individuals without due process or opportunity to challenge gang membership designations violates constitutional protections.
Trump administration uses archaic wartime law to deport hundreds without due process to El Salvador prison
Civil rights organizations and legal experts condemned the Trump administration's invocation of the 1798 Alien Enemies Act as an unprecedented abuse of emergency wartime authority during peacetime. The ACLU and Democracy Forward immediately challenged the deportations, arguing the government removed people without any opportunity to contest gang membership allegations or receive due process hearings. Judge Boasberg's temporary restraining order barred the deportations, but the administration defied the judicial order, with planes continuing to El Salvador while the judge's directive was supposedly in effect. The deportees were sent to a notorious maximum-security prison in El Salvador with histories of documented human rights abuses and torture. Lawyers and advocates argued the law was designed for interstate conflicts during declared wars, not immigration enforcement against criminal organizations. Judge Boasberg's subsequent findings of probable cause for contempt highlighted the administration's willful disregard for judicial authority and its rush to remove individuals before courts could intervene.
Key takeaway
The Alien Enemies Act cannot lawfully be used to deport individuals based on gang affiliation without due process, regardless of executive national security claims.
Right
The Trump administration argued Tren de Aragua operates as a hybrid criminal state aligned with Venezuelan President Nicolas Maduro, constituting an invasion threat, and that presidential authority under the Alien Enemies Act permits expedited removal without normal immigration proceedings.
Trump uses Alien Enemies Act to remove alleged gang members threatening national security
The Trump administration defended its invocation of the Alien Enemies Act as appropriate use of executive authority to address a grave national security threat. Officials argued Tren de Aragua operated as a criminal state controlled by Venezuelan President Nicolas Maduro and was engaged in mass migration designed to destabilize the United States. Attorney General Pam Bondi characterized the deportations as necessary defense against narco-terrorism and modern-day warfare. White House Press Secretary Karoline Leavitt stated the administration acted within legal confines and expressed confidence in winning the case. The Justice Department argued the planes carrying deportees had already left U.S. territory when Judge Boasberg's order was issued, making compliance impossible. Trump officials contended the judge overreached by inserting himself into foreign policy decisions and national security matters. The administration subsequently appealed court rulings blocking the deportations and called for the Fifth Circuit to reverse lower court decisions.
Key takeaway
The Trump administration possessed authority to prioritize national security through immigration enforcement, though implementation faced procedural and jurisdictional legal obstacles.
Straight
Trump invokes 1798 Alien Enemies Act, deports 238 Venezuelans, 137 under wartime law
President Trump on March 15, 2025, invoked the Alien Enemies Act of 1798 to order the rapid deportation of 238 Venezuelan nationals to El Salvador. Of these, 137 were removed under the 1798 statute as alleged members of Tren de Aragua, while 101 were deported under regular immigration law alongside 21 Salvadorans accused of MS-13 gang membership and two individuals described as gang leaders. The Trump administration claimed Tren de Aragua constituted a hybrid criminal state conducting an invasion of the United States. Federal Judge James Boasberg issued a temporary restraining order on the evening of March 15, directing any planes carrying deportees to return to the U.S., but the administration proceeded with the deportations to El Salvador's CECOT maximum-security prison. The Justice Department argued the flights had already left U.S. territory when the order was issued. In subsequent proceedings, Judge Boasberg found probable cause that the administration violated his court orders and held it in contempt. An appeals court later ruled the Alien Enemies Act did not apply to criminal gangs.
Key takeaway
The courts ultimately blocked peacetime application of the 1798 Alien Enemies Act to criminal organizations, though debate persists over executive power, due process, and national security.
The Analysis
Trump's March 2025 invocation of the Alien Enemies Act represented a dramatic expansion of a dormant statute, transforming a wartime law into an immigration enforcement tool. Legal challenges centered on three core questions: whether criminal organizations constitute foreign enemies under the 1798 law, whether due process rights apply despite the act's expedited procedures, and whether courts retain authority to review executive determinations of enemy status. The five-month legal battle revealed deep constitutional tensions between executive prerogative and judicial review. Early rulings by Judge Boasberg emphasized that even wartime powers require minimal procedural protections and that the statute's language contemplates actual invasion by foreign nations, not transnational gang activity. The September 2025 Fifth Circuit decision, authored by a George W. Bush-appointed judge, rejected the administration's theory that immigration could constitute invasion under the act's plain text. Significantly, the Supreme Court declined to address the underlying constitutionality, issuing narrow rulings on notice requirements instead. The administration's apparent defiance of Boasberg's March 15 order escalated the confrontation between branches, with Trump calling for the judge's impeachment and Boasberg finding probable cause for contempt. The eventual return of deported individuals via a Venezuelan prisoner exchange suggested the administration's legal position weakened over time.

Why It Matters
This decision tested whether presidents can unilaterally declare emergencies to bypass established legal protections for noncitizens and whether federal courts retain meaningful authority to restrain executive immigration power. The case established precedent regarding the scope of wartime statutes in peacetime and whether criminal organizations can trigger statutes designed for interstate conflicts. It also demonstrated judicial-executive tensions over foreign policy, national security claims, and the limits of presidential impeachment rhetoric.
