The morning began with intense focus on Donald Trump’s immediate retaliation against the U.S. Supreme Court, as he signed a 10% global tariff to bypass the judicial veto of his previous trade policy. Spanish editors initially analyzed this as a constitutional crisis, with El Mundo attributing the move to Trump’s waning control over Congress and the MAGA movement. By early afternoon, editorial priority shifted toward Spanish domestic politics. Sumar, Más Madrid, and Izquierda Unida formally launched a new 'confederal' alliance for the general elections, pointedly excluding Podemos while challenging the electoral strategy of ERC’s Gabriel Rufián. Simultaneously, La Vanguardia reported a breakdown in fiscal negotiations between the central government and ERC regarding Catalan income tax management. In the evening, the focus returned to Washington as Trump escalated his trade war further, raising the newly announced global tariff from 10% to 15% within twenty-four hours. This rapid acceleration dominated late-night headlines, overshadowing regional reports on Barcelona’s architectural status and Winter Olympic medal updates.
