"We can review what happens in other Latin American countries and what happens in our country. And this is a form of interference in Mexican politics . That is my opinion, because I see no other reason," she said.

Sheinbaum said there was no ongoing investigation against Lopez Beltran, but added that authorities would act if evidence of a crime emerged.

"We are not going to cover up anyone if they committed a crime," she said.

"But we are not going to open an investigation just because the US takes away someone's visa. So, what is the motive? The motive would be that we had a request, or an investigation stating that someone, some politician from any political party, was involved in some crime. Then the investigation continues and proceeds," she added.

Lopez Beltran disclosed the visa revocation in a letter addressed to US President Donald Trump . He claimed the decision was ordered by Secretary of State Marco Rubio and Deputy Secretary Christopher Landau.

He described the move as "political and propagandistic in nature" and with a "Hitlerian style", arguing that US officials had no evidence of "any immoral or criminal act."

Lopez Beltran also called the decision a "perverse outrage" and accused Landau and Rubio of acting like "gang leaders" who were "spying on, harassing, interfering with and harming" countries, governments and politicians they considered "communists, threats or narco-terrorists."

In May 2026, Lopez Beltran resigned as Organisation Secretary of Mexico's ruling Morena party and from his role on the National Elections Commission. He also announced plans to seek a federal deputy seat.
