# Petro probes: appointments, investigations, and scandals > Live situation record from CLSTR: https://clstr.news/situations/petro-family-corruption-probes-in-colombia > Updated: 2026-09-02T20:30:58.000Z. Sources: 92. Developments: 14. Investigations into President Gustavo Petro’s administration expanded significantly throughout July and August 2026. The Attorney General’s Office opened a formal investigation on 27 July into Juliana Guerrero and her sister, Verónica, for allegedly managing public contracts in exchange for bribes and commissions. The scheme reportedly targeted various ministries and agencies, including the National Land Agency. Guerrero has denied all wrongdoing, though Petro stated, “Juliana must answer to justice and the judges must decide on her titles,” while also defending the Adaptation Fund and labeling critic Angie Rodríguez a “manipulator”. Parallel probes have targeted Aerocivil following allegations from Rodríguez and deputy Daniel Briceño regarding Gabriela Muñoz Olaya. Prosecutors are examining whether Muñoz and several family members were hired through influence peddling and investigating a contract that swelled from 400 million to approximately 12 billion pesos. In response to controversy regarding Muñoz’s role as a communications coordinator, Petro denied rumors of a romantic relationship with her, stating their acquaintance began through her professional government contracts. He also noted that Muñoz has received death threats at her university. On 28 August 2026, Colombia’s National Protection Unit (UNP) withdrew security details for Gabriela Muñoz, Juliana Guerrero, and Beto Coral, citing insufficient justification for the costs. By early September, a new scandal emerged involving an alleged influence-peddling network dubbed ‘Mariposas amarillas’ (yellow butterflies). Former DAPRE Director Angie Rodríguez claimed that, with Petro’s approval, women in his inner circle, specifically naming Guerrero and Muñoz, received significant benefits. Additionally, investigative reports have linked María Masip Zawady to the network, alleging she increased her personal wealth through state contracts. ## Claims - Juliana and Verónica Guerrero operated a scheme to manage public contracts for payment.
