U.S. President Donald Trump has renewed his threat of tariffs against Canada over ongoing wildfire smoke drifting into the United States, further complicating relations between the two nations. As the Gordie Howe International Bridge nears its opening day, American celebrations are overshadowed by the contentious trade issue. The bridge is set to open despite last-minute demands from President Trump, adding to a series of tensions exacerbated by his administration's policies. Meanwhile, unrelated investigations into FIFA president Gianni Infantino have been rejected by the International Olympic Committee, with no plans for an inquiry into allegations of political interference in Olympic rules.
