Mexico is officially investigating whether the United States kidnapped a cartel kingpin off its soil, lied about it to the Mexican government, and then had the audacity to put the plane they used on display in an FBI museum exhibit. That last part is not a metaphor. The FBI literally turned the evidence into a tourist attraction.
The Plane, the Press Conference, and the Accusation
Here's how you know a diplomatic incident has gotten truly ugly: one country's president stands at a podium and says, on the record, that the other country's ambassador lied to her face. That's what happened Tuesday when Mexican President Claudia Sheinbaum told reporters that former U.S. Ambassador Ken Salazar almost certainly lied when he denied any U.S. agency involvement in the 2024 capture of Ismael "El Mayo" Zambada, co-founder of the Sinaloa cartel.
The whole thing unraveled, CBS News reports, after the FBI decided to display the plane used to fly Zambada into U.S. custody as part of some kind of exhibition. Congratulations to whoever made that call. You just handed Mexico a press conference.
"The versions are contradictory. Someone lied," said Mexican government secretary Rosa Icela Rodriguez. Sheinbaum was more direct: "Everything seems to indicate that the ambassador lied." That's not diplomatic language. That's a country telling you it's done pretending.
What Actually Happened When El Mayo Got Grabbed
The story of how Zambada ended up in U.S. custody is genuinely wild, and it only got weirder when the full details came out in court. Zambada was arrested in July 2024 alongside Joaquin Guzman Lopez, the son of "El Chapo" Guzman. When Guzman Lopez pleaded guilty to U.S. narcotrafficking charges last December, CBS News reports, he admitted to something remarkable: he had kidnapped Zambada himself, loaded him onto a plane, had him drugged, and flew him across the border as a gift to American law enforcement.
This was a betrayal inside one of the most violent criminal organizations on earth, and Guzman Lopez apparently thought it would buy him goodwill with U.S. prosecutors. Whether it did is a separate question. What it definitely did was blow up Mexico's official understanding of how the whole operation went down.
Zambada eventually pleaded guilty last August to federal charges covering drug trafficking, gun offenses, and money laundering. Federal prosecutors alleged he and other Sinaloa leaders were responsible for dumping massive quantities of heroin, cocaine, fentanyl, and other drugs into the United States. Nobody disputes that part. The dispute is about what the U.S. government knew, when it knew it, and whether it told its closest neighbor the truth.
This Is Just the Latest in a Very Bad Year for U.S.-Mexico Relations
The Zambada investigation isn't happening in a vacuum. It's the latest in a string of incidents that have pushed the relationship between Washington and Mexico City to a genuinely precarious place.
In April, CBS News reports, two CIA agents died under unclear circumstances during an anti-drug operation in the border state of Chihuahua. They were apparently operating without authorization from Mexico's federal government. Sheinbaum's administration opened an investigation into whether their presence violated national security laws. That investigation is still ongoing.
Days after the CIA incident became public, the U.S. Justice Department indicted the then-governor of Sinaloa state, Ruben Rocha Moya, along with nine other current and former Mexican officials on drug charges. Rocha Moya is a member of Sheinbaum's Morena party and a close ally of her political mentor, former President Andres Manuel Lopez Obrador. Sheinbaum responded by demanding the U.S. provide "irrefutable" evidence before she'd consider extraditing him. That's the diplomatic equivalent of telling someone to show their homework.
Trump Threatens Boots on the Ground While Mexico Tracks Cartels With U.S. Intelligence
Meanwhile, Donald Trump has been making noise about sending American troops into Mexico if Sheinbaum doesn't get her cartel problem under control. Sheinbaum has mostly responded by pointing out that Mexico is already doing the work, using U.S. intelligence to track narcotraffickers. In February, Mexican soldiers killed cartel boss Nemesio "El Mencho" Oseguera in a raid, CBS News notes, an operation that apparently relied on American intelligence.
So the situation is this: the two countries are cooperating on cartel enforcement while simultaneously accusing each other of lying, conducting secret operations, and potentially violating each other's laws. That's a partnership in the same way that two people arguing about the check while splitting an entree is a partnership. Technically functional. Deeply uncomfortable. One bad moment away from someone storming off.
The War Zambada's Arrest Unleashed Is Still Burning
Lost in the diplomatic noise is the human cost of what happened after Zambada got grabbed. His arrest shattered an uneasy internal balance inside the Sinaloa cartel. CBS News reports that the war between rival factions that followed has left thousands dead and missing.
Thousands. Since July 2024. That number deserves to sit on its own for a second.
Whatever the U.S. government intended when it facilitated or enabled or quietly watched Guzman Lopez drag his boss onto a plane, the consequences on the ground in Mexico have been catastrophic. Whether that outcome was anticipated, calculated, or completely ignored is one of the more uncomfortable questions buried inside this sovereignty investigation.
The Dingo Take
Let's be honest about what Mexico is actually alleging here. They're not just saying there was a miscommunication or a gap in information sharing. They're saying the United States government, through its embassy, actively lied to them about whether American agencies were involved in grabbing one of the most wanted men in the world off Mexican soil. And then the FBI put the plane on display. In an exhibition. For people to look at.
The U.S. has a long and mostly unacknowledged history of running operations in countries it considers friendly while telling those countries exactly nothing. Sometimes those operations work. Sometimes two CIA agents turn up dead in Chihuahua without apparent authorization from anyone in the Mexican government. The question of whether the ends justify those particular means is not one Washington seems interested in answering out loud.
Sheinbaum has a legitimate grievance here, and the fact that she's naming the ambassador personally and calling his statements lies is not nothing. She's also dealing with a Trump administration that has openly floated military incursions into her country, indicted her political allies, and apparently treated Mexican sovereignty as a bureaucratic inconvenience. The relationship is not in a good place. The FBI exhibit did not help.
