Brazilian Mayor Targeted in Major Corruption Sweep

Operation Sisamnes: Palmas Mayor's Home, Office Searched in Ongoing Corruption Probe Brazilian authorities carried out new searches on May 30, 2025, as part of Operation Sisamnes, a wide-ranging investigation into a suspected national network selling judicial sentences and leaking confidential information. The operation, authorized by Supreme Court Justice Cristiano Zanin, focused on the mayor of Palmas, Tocantins, Eduardo Siqueira Campos. Police searched Campos's home and the city hall, seizing unspecified materials. "The searches occurred at the mayor's house and at the city hall, with agents leaving the locations carrying briefcases," reported a news source. The investigation also involves Thiago Marcos Barbosa, the nephew of Tocantins Governor Wanderlei Barbosa, who was previously arrested in the operation. Authorities are investigating whether Barbosa received preferential treatment in prison. The investigation has already uncovered evidence of the sale of sentences in the Mato Grosso Court of Justice and the Superior Court of Justice (STJ). The operation highlights the ongoing fight against corruption in Brazil.
