Concerns regarding foreign interference in Brazil’s 2026 electoral process have escalated through reports from civil society and intelligence agencies. The Instituto Vladimir Herzog (IVH) alerted the United Nations to potential United States interference, warning of diplomatic pressures and the possibility that the Trump administration might contest election results. The IVH noted that the Brazilian Intelligence Agency (Abin) had already flagged American influence as being at a “critical level.”

Following these warnings, Abin officials met with delegations from France and Germany between September 9 and 11 to report suspected interference by both the United States and Russia. Officials described alleged U.S. actions as ranging from “lawfare”—the instrumentalization of the legal system—to “openly acknowledged interference.” While Russian involvement was also flagged, specific details regarding Moscow's alleged actions were not provided. These briefings occurred alongside discussions regarding the implementation of the European Union's Digital Services Act to coordinate international responses to harmful content.

The upcoming election features a tight race between President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro. In response to these threats, the Brazilian government is monitoring foreign lobbying and disinformation, while the Organization of American States (OAS) is deploying a mission of over 90 observers. The U.S. Department of State and the Russian Embassy have previously denied allegations of interference, and Abin and the Russian Embassy have declined to comment on specific recent allegations.
