President Claudia Sheinbaum asked U.S. Ambassador Ronald Johnson to stop intervening in the internal political affairs of Mexico [1].

The exchange marks a significant tension in diplomatic relations between the two neighbors. By establishing these boundaries, Sheinbaum is attempting to protect national sovereignty while ensuring that critical bilateral security cooperation remains intact [2].

Speaking in Mexico City on June 2, 2026 [3], Sheinbaum responded to statements made by Johnson that were perceived as interference in domestic policy [4]. The president said that diplomatic representatives should not offer opinions on the internal political workings of the host country [5].

"The affairs of Mexico only concern Mexicans," Sheinbaum said [6].

Sheinbaum said that the administration would not tolerate comments regarding the internal politics of the nation [7]. Despite the friction over diplomatic protocol, the president said that cooperation on security remains a priority for both countries, provided that such partnerships are built on respect for sovereignty [2].

"Diplomatic representatives must refrain from intervening or issuing opinions on internal political matters," Sheinbaum said [8].

The president said Johnson should keep his focus on bilateral themes and avoid the domestic political sphere [9]. This directive comes as Mexico continues to navigate complex security challenges that require U.S. assistance, creating a delicate balance between operational necessity and political independence [2].

"We are not going to allow comments on the internal politics of Mexico," Sheinbaum said [10].

"The affairs of Mexico only concern Mexicans."

This confrontation highlights the ongoing tension between U.S. diplomatic oversight and Mexico's insistence on sovereignty. By publicly rebuking Ambassador Johnson, Sheinbaum is signaling to both domestic audiences and the U.S. government that security cooperation is not a mandate for political influence. The outcome depends on whether the U.S. embassy adjusts its communication strategy to avoid further friction with the Mexican presidency.
