US Secretary of State Marco Rubio described Colombian President Gustavo Petro as “not very stable” during an end-of-year press conference in Washington, responding to questions about sharp rhetoric between the two governments. Rubio acknowledged repeated verbal clashes, noting that President Donald Trump has previously accused Petro of links to drug trafficking, while Petro has defended his administration’s anti-drug policies. The comments highlight ongoing diplomatic tensions between Washington and Bogotá, driven by disagreements over narcotics policy, leadership style and public statements, even as both sides continue official engagement and dialogue despite the strained tone in recent months.
