Ronald Johnson has officially been sworn in as the new United States Ambassador to Mexico, following a ceremony held in Washington, D.C. His appointment comes at a time of strategic importance for U.S.-Mexico relations, with cooperation on security, migration, and economic matters such as the U.S.-Mexico-Canada Agreement (USMCA) high on the bilateral agenda.
The American Society of Mexico welcomed Ambassador Johnson’s arrival with optimism. Larry Rubin, president of the organization, expressed confidence in Johnson’s qualifications and leadership. “He is a man of great integrity who will undoubtedly collaborate well with the new Mexican government,” Rubin said. “His background in intelligence and security will be key in strengthening the bilateral relationship.”
Johnson’s extensive public service career spans over four decades, including roles in the U.S. Army, the intelligence community, and diplomatic service. Most recently, he served as U.S. Ambassador to El Salvador. His prior assignments include serving as the CIA’s Science and Technology Liaison to the U.S. Special Operations Command, as well as a Special Advisor to the U.S. Southern Command. His work has encompassed regional challenges such as refugee crises, counter-narcotics, counterterrorism, human rights, and disease control.
Johnson began his military service in the Alabama Army National Guard in 1971 and later joined active duty in 1984, retiring as a Colonel in 1998. He holds a B.S. from the University of State University of New York and an M.S. from the National Intelligence University. His contributions have earned him multiple honors, including the Sue M. Cobb Award for Exemplary Diplomatic Service and the Joint Distinguished Civilian Service Award.
His appointment has been well received by both the American community in Mexico and bilateral stakeholders, who see his experience and leadership as valuable assets in maintaining and advancing strong U.S.-Mexico relations.
The U.S. Senate confirmed Ronald Johnson as Ambassador to Mexico in a 49–46 vote, with the outcome falling strictly along party lines. All votes in favor came from Republicans, while Democrats and independents aligned with them opposed the nomination. Only a simple majority of those present was required for confirmation, securing Johnson’s appointment to the high-profile diplomatic post under President Donald Trump’s endorsement.
