The Claim That Won’t Go Away: Did Other Countries Empty Their Mental Institutions Into the U.S.?

For years now, Donald Trump has repeated a startling assertion: that foreign governments—often described as “terrible countries”—deliberately emptied their prisons and mental institutions and sent those people into the United States during the presidency of Joe Biden.

The claim is vivid, frightening, and politically potent. It conjures images of coordinated state actions, sinister intent, and a nation under siege by people defined not by circumstance but by pathology. Trump has delivered versions of it at rallies, in interviews, and in speeches, often with only minor variations. Sometimes it is Venezuela. Sometimes it is “South America.” Sometimes it is simply “they.”

It is also not true.

What follows is a closer examination of the claim—where it came from, why it persists, and why it matters.

What Trump Actually Says

Trump’s phrasing is rarely precise, but the structure is consistent. Foreign countries, he claims, have:

• Closed or emptied mental institutions

• Released people with serious mental illness

• Sent them directly to the United States

• Taken advantage of a “weak” or “open” border under Biden

The claim is almost always delivered without evidence, documentation, or specificity. It relies instead on repetition and implication—an assertion that feels plausible only if one does not ask follow-up questions.

Is There Any Evidence This Happened?

No.

There is no evidence—from U.S. intelligence agencies, immigration authorities, international monitoring organizations, or foreign governments themselves—that any country systematically emptied mental institutions and sent patients to the United States.

Such an operation would require:

• National-level coordination

• International travel logistics

• Exit documentation

• Entry into U.S. asylum or immigration systems

• And, inevitably, a paper trail

None exists.

Not a memo. Not a whistleblower. Not a single verified case demonstrating state-directed mass transfers of psychiatric patients into the U.S.

Where the Idea Comes From

The claim appears to be a rhetorical mutation of two older narratives.

The first is a long-standing myth in American political culture that immigrants are disproportionately criminal or dangerous—an idea that has cycled through targets for over a century, from Irish Catholics to Italians to Mexicans to Muslims.

The second is a misremembered historical reference: in the 1980s, some Caribbean nations, including Cuba during the Mariel boatlift, released prisoners and psychiatric patients into broader migration flows. Even then, the numbers were limited, the context was specific, and the episode has been repeatedly mischaracterized and exaggerated over time.

Trump’s version removes all historical specificity and replaces it with a generalized, ongoing conspiracy.

What the Data Actually Shows

Studies of migration patterns during the Biden administration show:

• Migrants are primarily families, asylum seekers, and economic migrants

• The most common drivers are violence, political instability, climate disruption, and economic collapse

• There is no disproportionate prevalence of severe mental illness among migrants compared to host populations

In fact, migrants are more likely to be victims of violence than perpetrators, and many undergo medical and psychological screenings as part of asylum and resettlement processes.

Mental illness, where present, is far more often the result of trauma experienced during migration—not a reason for migration itself.

Why Trump Keeps Repeating It

The claim persists because it serves several purposes at once.

It:

• Dehumanizes migrants, reducing them to threats rather than people

• Absolves the speaker of policy responsibility, placing blame entirely on outsiders

• Invokes fear without requiring proof

• Collapses complex migration dynamics into a single villainous act

Most importantly, it reframes immigration not as a policy challenge, but as an invasion—one that justifies extraordinary responses.

The Subtle Shift: From Policy to Pathology

There is a deeper danger embedded in this claim.

By framing migrants as mentally unwell by default, the rhetoric does more than misinform—it pathologizes. It suggests that people crossing borders are not just lawbreakers or economic actors, but inherently unstable. This framing has historically been used to justify exclusion, detention, and abuse.

It is not an accident. It is a strategy.

Why This Matters

Falsehoods do not have to be elaborate to be effective. They only need to be repeated often enough, loudly enough, and without consequence.

Trump’s claim about mental institutions is not a throwaway line. It is a narrative that shapes public perception, influences policy debates, and hardens attitudes toward millions of people who have done nothing more than move in search of safety or survival.

There is no evidence that foreign countries sent their psychiatric patients to the United States during the Biden presidency. None.

What exists instead is a familiar pattern: a claim untethered from fact, sustained by repetition, and insulated from correction by the very outrage it produces.

This series will continue. Not because the claims are new—but because they refuse to disappear.
