IMMIGRATIONThe “Invasion” Invention: The Far Right’s Long Legal Battle to Make Immigrants the Enemy

The Trump administration is using the claim that immigrants have “invaded” the country to justify possibly suspending habeas corpus, part of the constitutional right to due process. A faction of the far right has been building this case for years.

When top Trump adviser Stephen Miller threatened on May 9 that the administration is “actively looking at” suspending habeas corpus in response to an “invasion” from undocumented immigrants, he was operating on a fringe legal theory that a right-wing faction has been working to legitimize for more than a decade.

“The Constitution is clear — and that of course is the supreme law of the land — that the privilege of the writ of habeas corpus can be suspended in a time of invasion,” Miller said earlier this month in response to a question about Trump’s threat to suspend habeas corpus, the legal right of a prisoner to challenge their detention. Days after Miller’s remarks, Homeland Security Secretary Kristi Noem issued the same warning when a member of a House panel asked her if the number of illegal border crossings meets the threshold for suspending the right. “I’m not a constitutional lawyer,” Noem said. “But I believe it does.”

Hard-liners have referred to immigrants as “invaders” as long as the U.S. has had immigration. By 2022, invasion rhetoric, which had previously been relegated to white nationalist circles, had become such a staple of Republican campaign ads that most of the public agreed an invasion of the U.S. via the southern border was underway.

Now, however, the claim that the U.S. is under invasion has become the legal linchpin of President Donald Trump’s sweeping anti-immigrant campaign.

The claim is Trump’s central justification for invoking the Alien Enemies Act to deport roughly 140 Venezuelans to CECOT, the Salvadoran megaprison, without due process. (The administration cited different legal authority for the remaining deportees.) The Trump administration contends they are members of a gang, Tren de Aragua, that Venezuelan President Nicolás Maduro is directing to infiltrate and operate in the United States. Lawyers and families of many of the deportees have presented evidence the prisoners are not even members of Tren de Aragua.

The contention is also the throughline of Trump’s day one executive order “Protecting the American People Against Invasion.” That document calls for the expansion of immigration removal proceedings without court hearings and for legal attacks against sanctuary jurisdictions, places that refuse to commit local resources to immigration enforcement.
