Spanish Prime Minister Pedro Sánchez has hosted two events in Barcelona to rally progressive leaders from around the world who fear for a rules-based world order. Sánchez and other attendees are outspoken critics of U.S. President Donald Trump. Trump chose Saturday to lash out on social media again at Sánchez, who has faced Trump’s scorn for not allowing the U.S. to use jointly operated military bases in Spain for operations related to the Iran war and for refusing to raise military spending. Democrats U.S. Sen. Chris Murphy and Minnesota Gov. Tim Walz were both present alongside the leaders of Brazil, South Africa, and high-ranking officials of other left-leaning governments.
