As U.S. authorities continue investigating possible ties between Mexican politicians and organized crime, intelligence agencies are reviewing reports that Senate credentials were granted to leaders of the Sinaloa Cartel who were listed as "advisers" linked to the Labor Party (PT) — a left-wing political group currently holding 49 deputies and nine senators in Mexico's legislature.
Journalist María Idalia Gómez, who spoke during a panel discussion with Carmen Aristegui and Anabel Hernández on Aristegui Noticias, claimed that more than 20 Senate credentials were issued by the Labor Party to members and leaders associated with Los Chapitos, the Sinaloa Cartel faction led by the sons of Joaquín "El Chapo" Guzmán.
As reported by Infobae México, the credentials identified cartel associates as advisers to the PT, though Gómez did not specify during which legislative session they were issued.
Gómez added that the investigation involves undercover U.S. agents who successfully infiltrated the Sinaloa Cartel. The evidence, she added, includes copies, photographs and videos now in the hands of U.S. intelligence agencies.
Curioso, muy curioso.

She also noted that the credentials contained photos of the holders and, in some cases, names that did not match their true identities. Investigators are now working to determine who facilitated the issuance of the documents and how individuals linked to organized crime were able to access official government identification.
While most of the evidence points to links with the Labor Party, Gómez said individuals from other political parties — including the ruling Morena party and the opposition National Action Party (PAN) — are also under scrutiny.
The United States has stepped up its investigations into Mexican public officials amid growing allegations of ties between high-ranking politicians and drug trafficking organizations.
In May, the Trump administration imposed travel restrictions on two Mexican governors suspected of drug-related corruption. Baja California Gov. Marina del Pilar Ávila and her husband — a former congressman — had their U.S. visas revoked. Mexican media also reported that Tamaulipas Gov. Américo Villarreal had his visa canceled.
In June, Sonora Gov. Alfonso Durazo came under scrutiny after a local journalist reported that U.S. authorities had flagged him as a "suspected terrorist," a designation that could carry an immediate arrest order.
The country's most emblematic case remains that of former Public Security Secretary Genaro García Luna, who was convicted in February 2023 by a U.S. federal jury in Brooklyn on charges of running a continuing criminal enterprise, international cocaine distribution, and making false statements. In October 2024, he was sentenced to 38 years in federal prison and fined $2 million for accepting bribes from the Sinaloa Cartel and facilitating the smuggling of more than a million kilograms of cocaine into the United States.
