President Trump’s use of the Alien Enemies Act to deport suspected gang members faces legal challenges.

Trump believes that the alarming human trafficking issues, the large number of fentanyl overdose deaths, and the spike in crimes committed by illegal immigrants justify the extreme measure of invoking this law.   

Trump’s Invocation of Wartime Powers

Trump invoked the Alien Enemies Act in March 2025, citing what he described as an invasion of criminals and gang members entering the U.S. under the Biden administration.

“This is a time of war. Because Biden allowed millions of people, many of them criminals, many of them at the highest level. Other nations emptied their jails into the United States, it’s an invasion. These are criminals, many many criminals … murderers, drug dealers at the highest level, drug lords. People from mental institutions. That’s an invasion,” Trump said.

Trump specifically accused the Tren de Aragua, a Venezuelan gang, of operating in the U.S. “at the direction, clandestine or otherwise, of the Maduro regime in Venezuela.”

Based on this claim, Trump deported over 200 men suspected of gang involvement to a prison in El Salvador.

What Is the Alien Enemies Act?

The Alien Enemies Act was passed in 1798, alongside the Naturalization Act, Sedition Act, and Alien Friends Act, during rising tensions with France. The law has remained on the books for more than two centuries, rarely used until Trump’s recent actions.

The Alien Enemies Act, first signed into law as part of the Alien and Sedition Acts, allows the president to detain and deport immigrants from enemy nations during wartime, with no requirement to show evidence of disloyalty or criminal behavior.

The law states that “whenever there shall be a declared war...or any invasion or predatory incursion shall be perpetrated, attempted, or threatened” against the United States, all “subjects of the hostile nation or government” can be “apprehended, restrained, secured and removed, as alien enemies.”

Intelligence Memo Contradicts  

A declassified memo from U.S. intelligence agencies, released by the Freedom of the Press Foundation, contradicts Trump’s justification.

The intelligence assessment concluded:

“Venezuelan President Nicolas Maduro’s government doesn’t direct all of Tren de Aragua's activities.”

This undermines the Trump administration’s claim that Venezuela constitutes an “enemy nation” actively controlling the gang’s actions within the U.S.

Legal Pushback Mounts

Legal experts are challenging Trump’s use of the Alien Enemies Act, arguing that the United States is not in a declared war.

“We haven’t had a declared war,” said Steve Vladeck, a Georgetown University law professor. “And no one has tried to argue that that invasion or predatory incursion language could be used in any context other than a conventional war.”

Before Trump, the law had only been invoked three times in U.S. history, always during formally declared wars.
