Live updates: Supreme Court denies GOP on Missouri map suit; Canadian tariffs, Trump threats grow trade war

A single-member order from Supreme Court Justice Brett Kavanaugh on Tuesday declined to remove a lower-court injunction that had kept Missouri’s recently drawn congressional map from taking effect. With that request denied, the state will proceed to use its current U.S. House plan, a 6-2 map that has favored Republican candidates, in the November contest. The blocked map had been viewed as creating an opening for Republicans to gain a seat in November. By leaving the injunction in place, the court’s action preserves the status quo electoral boundaries and leaves candidates and party strategists to plan for races under the existing district lines. Separately, relations between the United States and Canada have grown more strained as Ottawa implemented retaliatory tariffs targeting U.S. goods. Those measures, combined with public threats from President Donald Trump, have heightened the trade dispute between the two countries. The combination of the Missouri ruling and the expanding trade confrontation underscores how legal and policy developments coming from courts and capitals can quickly reshape political and economic landscapes. Voters in Missouri will head into the election under the earlier map, while companies and consumers on both sides of the border may face the consequences of an escalating tariff standoff.
