The Claim

Achieved a 99% year-over-year collapse of Darién Gap migration traffic, stemming the tide of illegal alien traffic directly at the source.

The Claim, Unpacked

What is literally being asserted?

Two distinct factual claims: (1) Darién Gap migration traffic declined by 99% year-over-year; (2) the U.S. administration accomplished this by acting “directly at the source.” The verb “achieved” attributes this outcome to the administration making the claim.

What is being implied but not asserted?

That the Trump administration caused this collapse through its own actions. That the Darién Gap is the “source” of illegal migration to the United States. That reducing Darién crossings equates to reducing overall migration. That this is an unambiguous win.

What is conspicuously absent?

Any mention of Panama’s sovereign role in closing the Darién Gap — President José Raúl Mulino, who took office on July 1, 2024 (seven months before Trump), pledged to close the route and began doing so immediately. No mention that the Biden administration signed the U.S.-Panama deportation agreement on July 1, 2024. No mention that crossings had already declined 41% in 2024 before Trump took office. No acknowledgment of route displacement — migrants shifting to sea routes and other corridors rather than ceasing migration. No mention of the reverse migration phenomenon (22,000+ migrants traveling southbound through Panama in 2025). No mention of the humanitarian toll or the root causes that continue to drive migration from Venezuela, Haiti, and elsewhere.

Evidence Assessment

Established Facts

Darién Gap crossings collapsed by approximately 99% in 2025 compared to 2024. Panama’s National Migration Service (Servicio Nacional de Migración, SNM) recorded 2,941 crossings from January through August 2025, compared to 302,203 for all of 2024. Monthly figures show an accelerating decline: January 2025 saw 2,229 crossings, dropping to 408 in February, 194 in March, 73 in April, 13 in May, and just 10 in June. The DHS itself reported a 99.98% decline when comparing June 2025 (10 crossings) to the peak month of August 2023 (~82,000). Panama’s President Mulino confirmed the 99% figure in December 2025. [^015-a1]

The decline in Darién crossings began under Panama’s President Mulino in July 2024, six months before Trump took office. Mulino was inaugurated on July 1, 2024 after campaigning on a promise to close the Darién Gap. In his first month, crossings fell 34% from June. By the end of 2024, total crossings were 302,203 — a 41% decline from 2023’s record 520,085. Key Panamanian enforcement actions included closure of jungle trails, deployment of security forces, shuttering of migrant transit centers, and deportation flights. [^015-a2]

The Biden administration signed the U.S.-Panama deportation agreement on July 1, 2024 — the day of Mulino’s inauguration. The U.S. pledged $6 million for migrant repatriations, dispatched DHS officials with asylum screening and deportation experience to Panama, and provided equipment and logistics support. This was the first time the United States paid directly for another country’s removal flights. Approximately 1,548 migrants were repatriated on U.S.-backed flights in 2024. This agreement predated the Trump administration by seven months. [^015-a3]

MSF (Doctors Without Borders) concluded all operations in Panama in September 2025 after nearly four years, citing the drastic drop in migration flows. From April 2021 to August 2025, MSF conducted 163,000 medical consultations, 8,100 mental health consultations, and treated 1,955 survivors of sexual violence. In June 2025, MSF launched a three-month emergency response in Colón province to assist migrants in reverse flow from North America to South America by sea — predominantly Venezuelans. The closure of a major humanitarian organization’s operations corroborates the scale of the decline. [^015-a4]

Strong Inferences

Panama’s President Mulino explicitly claimed credit for the decline, contradicting the Trump administration’s attribution. In March 2025, Mulino stated his administration is “the one behind the decline” after ordering closure of migrant transit centers along the Darién Gap, declaring: “We will not allow more migrants in the Darién region, and we are closing an operation that began in 2016.” In December 2025, Mulino announced Panama was “closing the year with the lowest levels of irregular migration recorded in the past 13 years,” citing his operations Plan Firmeza and Operation Centinela. Both the Trump administration and Panama’s government claim the decline as primarily their accomplishment. [^015-a5]

Route displacement occurred: migrants shifted to sea routes rather than ceasing migration entirely. Migrants began boarding speedboats from Panama’s Colón province on 12-hour sea journeys to Colombia’s La Miel at approximately $280 per person. In February 2025, a boat capsized killing an eight-year-old Venezuelan child. MSF launched emergency operations in Colón province specifically to assist migrants using these maritime routes. By June 2025, approximately 7,696 southbound migrants had traveled from Panama to Colombia since February. Over 2,800 migrants in Mexico requested UN assistance to return home in January-February alone. 22,000 migrants returned through Panama to their countries of origin during 2025. [^015-a6]

The Gulf Clan (Gaitanistas), Colombia’s largest criminal organization that controlled Darién smuggling routes, adapted rather than disappeared. InSight Crime reported the Gulf Clan earned up to $100 million from migrants in 2024, but this revenue stream collapsed in 2025. However, the same criminal networks pivoted to offering southbound passage and maritime routes, charging at least $230 per person. The smuggling infrastructure remained intact even as the primary revenue stream shifted direction. [^015-a7]

Multiple causal factors contributed to the decline, not a single policy. The timeline shows: (1) Panama’s Mulino began enforcement in July 2024; (2) the Biden-era U.S.-Panama agreement provided funding and logistics from July 2024; (3) crossings were already falling through H2 2024; (4) Trump’s inauguration in January 2025 and shutdown of CBP One and asylum pathways accelerated the final collapse; (5) Colombia’s enforcement operations continued; (6) the deterrent effect of mass deportations reduced demand for northbound transit. The steepest decline (from 2,229 in January to double-digits by May) coincides with Trump’s first months, but it accelerated a trend that had been established for six months. [^015-a8]

Informed Speculation

The CSIS analysis warned that closure attempts would push migrants to “more clandestine — and more dangerous — routes.” The emergence of maritime routes with at least one child fatality, the reverse migration phenomenon, and the adaptation of criminal smuggling networks suggest this prediction was correct. The 99% decline in Darién crossings almost certainly overstates the actual reduction in hemispheric migration, because an unknown number of migrants shifted to alternative corridors rather than abandoning their journeys entirely. However, quantifying the degree of route displacement versus genuine deterrence is not yet possible with available data.

The root causes driving migration — economic collapse in Venezuela (7.7 million displaced), instability in Haiti, poverty in Ecuador and Colombia — have not changed. As the St Andrews Economist and others note, the underlying push factors “prevail as most of Latin America continues to be socially, economically and politically unstable.” The Darién closure does not address these causes; it closes one visible corridor.

Structural Analysis

Cui bono from the framing: The claim attributes a multinational, multi-actor outcome to a single administration. The Darién Gap is in Panama and Colombia, not the United States. The critical enforcement actions — trail closures, military deployments, transit center shutdowns, deportation flights — were executed by Panamanian security forces on Panamanian soil, initially supported by a Biden-era agreement. By claiming to have “achieved” this “at the source,” the administration appropriates the work of a sovereign foreign government and erases the Biden administration’s foundational role.

Stated vs. revealed preferences: The phrase “directly at the source” implies the administration acted in the Darién itself. In reality, U.S. influence was indirect: deterrence through domestic policy changes (asylum shutdown, mass deportations) reduced demand for northbound transit, while the pre-existing U.S.-Panama agreement provided logistical support. The actual boots on the ground were Panamanian.

The attribution problem: Both the Trump and Mulino administrations claim credit. The evidence suggests a causal chain with multiple necessary conditions: (1) Mulino’s willingness to close the route (Panama’s sovereign decision); (2) U.S. financial and logistical support (Biden-era agreement); (3) Trump’s domestic deterrence through asylum shutdown and deportation acceleration (reduced demand); (4) Colombia’s continued enforcement. Removing any of these factors might have produced a different outcome. The claim attributes 100% of a multi-factor result to one actor.

Follow the money: The $6 million Biden-era funding for Panama’s deportation flights was modest but symbolically important — it represented the first time the U.S. directly paid for another country’s removal operations. This created a template that the Trump administration expanded. The smuggling economy collapsed from ~$100 million annually to near-zero in the Darién, but the criminal networks adapted to maritime routes.

The denominator problem: The Darién Gap was one migration corridor among several. Closing it dramatically is a real operational accomplishment, but the implied narrative — that hemispheric migration was “stemmed at the source” — conflates one route with the total migration system. The “source” of migration is the conditions in Venezuela, Haiti, Ecuador, and elsewhere, not the jungle corridor through which people fled those conditions.

Context the Framing Omits

The 41% decline in 2024 preceded Trump’s inauguration. From 520,085 in 2023 to 302,203 in 2024, the Darién decline was well underway under Mulino’s enforcement and the Biden-era agreement. The further acceleration in 2025 built on this existing momentum.

Panama’s president publicly rejects the attribution. Mulino’s March 2025 statement that his administration is “the one behind the decline” directly contradicts the White House’s implicit claim of sole credit.

Reverse migration is a new humanitarian crisis. 22,000+ migrants traveled southbound through Panama in 2025, many returning to the countries they fled. MSF launched emergency operations for these returnees. Anthropologist Caitlyn Yates described reverse migration as potentially more traumatic than the northbound journey, noting migrants carry “grief and trauma of having crossed through the Darién” combined with “the end of hope.”

The Darién Gap is one of the most dangerous migration routes in the world. Between 2021 and 2024, over 1.2 million people crossed it. MSF treated 1,955 survivors of sexual violence during this period. At least 55 migrants died in the Darién in 2024 alone, and 180 children were abandoned. Reducing crossings through this specific route may have saved lives — but route displacement to maritime corridors has already produced at least one child death, suggesting danger was redirected rather than eliminated.

Trump’s foreign-aid freeze damaged the humanitarian response. Type Investigations reported that the freeze “dismantled Costa Rica’s protection system within four months.” Faith-based organizations filled gaps, with nuns in Paso Canoas providing meals to 100+ daily southbound migrants. The collapse of humanitarian infrastructure along the route happened simultaneously with the migration shift.

Verdict

Factual core: Mostly true. The approximately 99% year-over-year decline in Darién Gap crossings is real and well-documented by Panama’s own migration authority, corroborated by DHS, MSF, and multiple independent journalists. The number went from 302,203 in 2024 to approximately 2,941 (Jan-Aug 2025). This is a genuine, dramatic collapse of a major migration corridor.

Framing as “win”: Misleading on attribution. The claim uses “achieved” to attribute a multinational outcome primarily to a single administration. The decline resulted from at least four interacting factors: (1) Panama’s sovereign enforcement under Mulino (began July 2024); (2) the Biden-era U.S.-Panama agreement (signed July 2024); (3) Trump’s domestic deterrence through asylum shutdown and deportation acceleration (January 2025); (4) Colombia’s enforcement cooperation. The Trump administration’s policies — particularly the elimination of asylum pathways and the deterrent effect of mass deportations — clearly accelerated the final collapse, but they did not “achieve” this unilaterally.

The phrase “directly at the source” is doubly misleading: the Darién Gap is not the “source” of migration (conditions in Venezuela, Haiti, and elsewhere are), and the U.S. did not act “directly” in the Darién (Panama’s security forces did, on Panamanian soil). Further, the claim omits route displacement — migrants shifting to dangerous maritime corridors and reverse migration routes — which means the 99% figure overstates the actual reduction in hemispheric migration.

What a reader should understand: Darién Gap crossings did collapse by approximately 99% in 2025. This is real. But the decline was a joint accomplishment of Panama’s Mulino government (which both started the crackdown and claims primary credit), a Biden-era U.S.-Panama agreement, Trump-era domestic deterrence, and Colombian enforcement. The Trump administration’s contribution was significant but not sole or even necessarily primary. The migration itself did not disappear — it shifted direction and route, creating new humanitarian crises that the original claim erases.
