Left-wing supporters caused a disturbance in Santiago following José Antonio Kast's presidential victory in the December 14 runoff, according to an X post by AlertaNews24 shared between 4:16 a.m. and 5:45 a.m. UTC on December 15, 2025. The incident occurred after early results showed Kast defeating Jeannette Jara with 59.83% to 40.17%, as previously reported by AlertaNews24. Thousands of right-wing supporters had celebrated the outcome in Santiago streets earlier, wearing MAGA hats, per X user @EricLDaugh during the prior reporting window ending at 4:16 a.m. UTC. X user @agusantonetti commented on Colombian President Gustavo Petro's multiple posts reacting to the result, including warnings of 'winds of death,' in a post shared over the two hours ending at 4:15 a.m. UTC. U.S. Secretary Rubio congratulated Kast late December 14, anticipating partnership on security and trade.
