Recent court filings in Mexico have drawn fresh scrutiny to two sons of former President Andrés Manuel López Obrador, known as AMLO, over their alleged connections to a sprawling fuel theft and smuggling operation linked to powerful cartels.
Documents obtained by the news outlet Latinus reveal that Andrés Manuel “Andy” López Beltrán and Gonzalo “Bobby” López Beltrán secured federal injunctions to shield themselves from potential arrest warrants. These legal maneuvers, often called “amparos,” were granted by judges in Mexico City and Zacatecas, extending protection not just to the brothers but to 14 others implicated in the scheme.
The injunctions block immediate detention, forced disappearance, torture, or incommunicado holding, and they compel authorities to disclose any existing arrest orders. Court records show the filings targeted the Specialized Prosecutor’s Office for Organized Crime within Mexico’s Attorney General’s Office. Yet the lawyer named in the documents, Juan Francisco Rodríguez Smith Macdonald, has publicly disavowed any involvement.
“I did not file the proceedings,” he told El Universal, insisting that someone had usurped his identity. This denial adds a layer of intrigue, raising questions about who might be orchestrating these protections and why.
The brothers’ involvement reportedly stems from their use of political influence to facilitate a network smuggling cartel-stolen fuel through Mexican ports under Navy control. Reports suggest they leveraged their positions during their father’s administration to enable large-scale shipments via tankers, bypassing customs and evading taxes. This operation falls under the banner of “huachicol fiscal,” a term for sophisticated fuel fraud that has drained billions from Mexico’s state-owned oil company, Pemex. Over the past five years alone, such thefts have cost Pemex $3.8 billion, with stolen or smuggled fuel often resold domestically or across the border.
President Claudia Sheinbaum, AMLO’s successor and a close ally, swiftly rejected the allegations during a September 18 press briefing.
“They already denied that they [Andrés Manuel and Gonzalo López Beltrán] filed for legal protection. There’s a lawyer who said he didn’t file anything either,” Sheinbaum stated. “This is part of a smear campaign, plain and simple. It’s a political attack against our movement, against President López Obrador, and against his sons.”
Her defense echoes the family’s own statements. Andrés Manuel López Beltrán posted a letter on social media denying any role in seeking the injunctions and labeling the reports a “fabrication” by opponents.
“This entire matter is part of a smear campaign attempting to link me and my family to criminal activity,” he wrote. “We not only have no connection to it, we fully support continued efforts to dismantle these networks.”
He added, “As always, we stand by the decisions of our President, Claudia Sheinbaum Pardo, and reaffirm our commitment to the actions taken to address this national security challenge.”
Despite these denials, the scandal has widened to engulf high-ranking Navy officials, exposing what appears to be entrenched corruption. Earlier this month, authorities arrested Vice Admiral Manuel Roberto Farías Laguna and his brother, Rear Admiral Fernando Farías Laguna, for allegedly heading a bribery ring at the port of Tampico in Tamaulipas. Prosecutors claim the brothers coordinated with customs officials to allow illicit diesel tankers through in exchange for bribes up to $90,000 per shipment. A protected witness, a former customs director, testified that six such tankers docked up to 14 times with full complicity from port staff.
The probe has taken a darker turn with suspicious deaths tied to the case. Two Navy captains linked to the investigation died under unclear circumstances shortly after arrests began. One whistleblower, Rubén Guerrero Alcántara, was gunned down in November 2024 after reportedly alerting Navy Secretary Rafael Ojeda Durán—uncle to the Farías brothers—about port irregularities. These events fuel suspicions that the network reaches into the highest echelons of power, protecting cartel interests.
Security experts argue that such operations cannot thrive without broad institutional backing.
“Huachicol networks require a level of political, military and police protection,” explained Mexican security analyst David Saucedo.
This protection enables cartels like the Jalisco New Generation Cartel (CJNG) to expand their fuel theft activities, which in turn fund deadlier ventures such as fentanyl production and trafficking. The U.S. Treasury Department sanctioned nine Mexican nationals and 26 entities tied to CJNG’s fuel operations in September 2024, noting how stolen oil bolsters the group’s global reach.
On the U.S. side, the Department of Justice has pursued related cases, including charges against Texas oil company owners for using false documents to move cartel fuel. Mexican officials insist the arrests signal a serious crackdown. Security Secretary Omar García Harfuch defended the Navy, saying, “the actions of a handful of isolated people doesn’t mean they’re acting in the name of a respectable institution.”
But critics contend these moves merely reveal the pervasive rot within Mexico’s institutions, especially under administrations that have promised reform yet delivered uneven results.
As Sheinbaum’s government navigates this fallout, the allegations against AMLO’s sons test the boundaries of accountability. With cartels gaining from fuel smuggling to finance cross-border crime, the scandal serves as a reminder of the intertwined fates of Mexico and the United States in combating organized corruption. Ongoing investigations may yet clarify the full extent of these ties, but for now, the injunctions and denials keep the controversy alive.
