A false claim circulating on social media asserted that Colombian President Gustavo Petro assumed the presidency of the UN Security Council after completing his term as president of Colombia. Fact-checkers have deemed this information misleading. While President Petro did preside over the Security Council, the position operates on a monthly rotational basis among its member states. Colombia held the presidency for the month of June only. The claim of a longer-term assumption of the role is inaccurate. This highlights the spread of misinformation, even concerning international organizations like the UN. The rotational system ensures equitable representation and leadership within the Security Council.
