A previously orderly United Nations General Assembly session focused on the decades-long U.S. economic, trade and financial embargo against Cuba devolved into a chaotic, shouting-filled altercation on Tuesday, October 27, 2026, culminating in Washington’s formal expulsion of a Cuban diplomatic official, escalating already frayed bilateral tensions under the current Trump administration. The outburst was triggered when U.S. Ambassador to the UN Mike Waltz took the floor to urge all member states to reject the annual non-binding resolution that condemns the long-running U.S. restrictive policy targeting the Caribbean island nation. During his address, Waltz leveled public corruption allegations against Cuba’s socialist governing body, displaying physical evidence including photographs of former Cuban leader Fidel Castro wearing luxury Rolex timepieces, as well as imagery of a private island reportedly owned by the Castro family. The remarks immediately sparked fury among the Cuban delegation: Foreign Minister Bruno Rodríguez and other Cuban representatives slammed their fists on their conference tables, shouted for a procedural point of order, before Rodríguez walked directly to the speaker’s podium to yell directly at Waltz, “You are a liar!” An enraged Waltz immediately pushed back, shouting that the Cuban diplomat could not intimidate him on U.S. territory the same way Cuban authorities allegedly intimidate political prisoners, demanding Rodríguez step away from the podium while emphasizing his status as the official U.S. representative to the global body. The unprecedented verbal clash forced the General Assembly president to temporarily suspend the full proceedings to restore order. Once the session resumed, Rodríguez publicly labeled Waltz an “arrogant liar” before the full chamber. Following the floor confrontation, Waltz issued formal accusations that an unidentified Cuban diplomatic staffer had attempted to disable his speaking microphone and block his team from recording the altercation. He announced that U.S. Secretary of State Marco Rubio had formally ordered the expulsion of that Cuban official, who is required to depart for Havana within a 24-hour window. Rodríguez later took to social media platform X to fire back, noting that Waltz had forgotten the neutral, international nature of the UN headquarters premises, rather than treating the space as exclusively U.S. sovereign territory. This dramatic diplomatic breakdown unfolds against a backdrop of the Trump administration ramping up maximum pressure campaigns against Havana: as early as January 2026, U.S. leadership threatened sweeping punitive tariffs against any nation that supplied oil to Cuba, a move that has effectively choked off most of the island’s fuel imports and triggered widespread, extended blackouts across Cuban residential and commercial areas. Later on the day of the confrontation, the General Assembly proceeded to vote on the annual anti-embargo resolution, passing it with 130 member states voting in favor, 17 voting against, and 25 choosing to abstain. The 2026 vote marked a sharp drop in support compared to the previous year’s tally of 165 yes votes, 7 no votes, and 12 abstentions, marking the 34th consecutive time the non-binding resolution has been adopted by the global body.
