“President Donald Trump claims that the Alien Enemies Act of 1798 grants him the power to deport certain Venezuelan-born aliens without due process, based on the mere allegation of membership in a criminal street gang.
But the text of the Alien Enemies Act does not allow the president to do anything of the sort. “Whenever there shall be a declared war between the United States and any foreign nation or government, or any invasion or predatory incursion shall be perpetrated, attempted, or threatened against the territory of the United States, by any foreign nation or government,” the act states, the president may direct the “removal” of “all natives, citizens, denizens, or subjects of the hostile nation or government, being males of the age of fourteen years and upwards, who shall be within the United States, and not actually naturalized.”
The crimes of the alleged members of the street gang Tren de Aragua do not meet this legal standard. There is no “declared war” between the United States and Venezuela, and there is no “invasion or predatory incursion” of the U.S. by “any foreign nation or government.” The gang is not a foreign state, and the gang’s alleged crimes, heinous as they may be, do not qualify as acts of war by a foreign state. Trump’s frequent talk about a rhetorical “invasion” of the U.S. by undocumented immigrants utterly fails to satisfy the law’s requirements.”
