A supervisor at the Drug Enforcement Administration's office in the Dominican Republic was taken into custody as part of a federal investigation into the abuse of a U.S. visa program designed for confidential informants.

According to The Post, the arrest of Melitón Cordero, led by the Department of Homeland Security, prompted U.S. Ambassador Leah F. Campos to shutter the DEA's entire Dominican Republic office until further notice.

Ambassador Campos didn't mince words. In a post on X, she laid down a marker:

"It is a disgusting and disgraceful violation of public trust to use one's official capacity for personal gain. I will not tolerate even the perception of corruption anywhere in the Embassy I lead."

That's not diplomatic boilerplate. That's a line in the sand — and exactly the posture Americans should expect from their representatives abroad.

A Program Ripe for Exploitation

The investigation centers on a visa program that allows the DEA, FBI, and other federal law enforcement agencies to sponsor the entry of foreign nationals into the United States — individuals who might otherwise be deemed inadmissible because of their ties to criminal activity. Every year, hundreds of foreign nationals enter the country under this program.

The logic behind the program is straightforward: sometimes you need people with criminal connections to help dismantle criminal networks. The problem is what happens when the gatekeepers become the grifters.

A 2019 Justice Department watchdog report found that law enforcement had lost track of as many as 1,000 sponsored individuals — people with known involvement in criminal activity, now somewhere inside the United States with no one keeping tabs. The report identified the situation as posing risks to both public safety and national security.

One thousand people with criminal backgrounds, admitted through official channels, then lost. That's not a paperwork issue. That's a systemic failure baked into a program that hands extraordinary power to individual agents and supervisors with minimal accountability.

Cleaning House

The details surrounding Cordero's arrest remain thin. No specific charges have been publicly identified. Neither the DHS nor the DEA responded to requests for comment. Messages to Cordero's cellphone went unanswered.

What we do know is that the Trump administration moved swiftly. The DHS led the investigation, the ambassador closed the office, and the language from U.S. officials left no doubt about how seriously they view the breach. Dominican Foreign Affairs Minister Roberto Álvarez confirmed that the closure had nothing to do with the Dominican government and was part of an internal U.S. investigation—a useful clarification that underscores the real target: corruption within American institutions, not any breakdown in bilateral relations.

That distinction matters because U.S.-Dominican cooperation on counter-narcotics has been strengthening. Dominican President Luis Abinader recently authorized U.S. government personnel to operate inside restricted areas at San Isidro Air Base and Las Américas International Airport to assist in fighting drug trafficking. That kind of cooperation doesn't happen without trust — and trust requires that the American side of the partnership keep its own house clean.

The Deeper Problem

For years, Washington's national security apparatus has operated with a dangerous assumption: that the people running sensitive programs are inherently trustworthy because they hold a badge. The 2019 watchdog report should have been a five-alarm fire. Losing a thousand criminal informants inside American borders isn't a rounding error. It's evidence that the program lacked the basic oversight mechanisms any serious institution would demand.

And yet here we are, years later, with a DEA supervisor arrested for allegedly exploiting the very same type of program.

This is what happens when bureaucracies prioritize operational convenience over accountability. Visa programs that grant entry to criminals require ironclad controls — not because the concept is inherently wrong, but because the incentive structure for abuse is obvious. A federal employee with the power to sponsor a foreign national's entry into the United States holds something enormously valuable. Without rigorous oversight, that power becomes currency.

Action Over Posture

The Trump administration's response here deserves recognition not for its rhetoric but for its mechanics. The investigation was already underway. The arrest was executed. The office was closed the same day. Ambassador Campos didn't issue a vague statement about "reviewing processes" or "convening a working group." She shut the operation down.

That's the difference between an administration that tolerates institutional rot and one that excises it. Corruption inside federal law enforcement — particularly in agencies operating on foreign soil with enormous discretionary power — is not a problem you study. It's a problem you solve.

The DEA's Dominican Republic office will presumably reopen once the investigation runs its course. When it does, the question won't be whether one bad actor was caught. It will be whether the program that made his alleged conduct possible has been rebuilt to prevent the next one.

A thousand lost informants in 2019. An arrested supervisor now. The pattern doesn't require a watchdog report to see.
