US federal prosecutors in Manhattan and Brooklyn have conducted investigations since at least March 2026 into Gustavo Petro’s alleged ties to drug traffickers, including possible campaign donations and meetings linked to narcotics networks, with the DEA designating him a priority target. These probes remain in early stages with no public indictments or charges filed as of mid-October 2026. Separate October 2025 OFAC sanctions under Executive Order 14059 for alleged illicit drug involvement continue to apply to Petro and associates, though they represent administrative measures rather than criminal proceedings. Petro has denied the allegations, and US officials have stated no charges are pending. The absence of recent escalations or scheduled milestones keeps implied probabilities for near-term US criminal charges low among traders.
