US federal prosecutors in Manhattan and Brooklyn opened narcotics-related investigations into former Colombian President Gustavo Petro in early 2026, examining alleged meetings with traffickers and campaign donations, though officials clarified at the time that no charges had been filed and the probes remained preliminary. Petro, who left office on August 7, 2026, faces OFAC sanctions imposed in late 2025 over drug-trade allegations. More recently, Ecopetrol launched an internal review of over 30 alleged irregularities from his administration, with findings potentially referred to the US DOJ and SEC due to the company’s NYSE listing and securities compliance obligations. Separate reports note an Ecuadorian figure planning cooperation with US authorities that could reference Petro, though no formal US indictment has resulted. These threads, alongside Colombia’s new administration’s cooperation on extraditions, shape ongoing trader assessments of charging prospects.
