President Donald J. Trump has announced plans to invoke the Alien Enemies Act of 1798, a rarely used law originally designed for wartime security, in a sweeping move to expedite deportations of specific immigrant groups. The decision, which legal experts warn could face significant constitutional challenges, marks one of the most aggressive immigration enforcement measures of his presidency.
A Law From the Past With Modern Consequences
The Alien Enemies Act, one of the four laws collectively known as the Alien and Sedition Acts, was signed into law by President John Adams in 1798. It grants the executive branch the authority to detain, relocate, or deport foreign nationals from hostile nations during times of war. Historically, it has been used sparingly, most notably during the War of 1812 and World War II when enemy aliens were interned or removed from the country.
President Trump’s move to invoke the act in peacetime is unprecedented. White House officials have indicated that the administration will argue the United States faces security threats from individuals who may pose risks, despite not being engaged in a formal war.
