Live updates: US-Canada trade war details surface; Trump to take honor lap in IndyCar Grand Prix

Trade tensions between the U.S. and Canada are escalating as details of failed negotiations emerge, leading to retaliatory tariffs of 50% on certain goods. U.S. Trade Representative Jamieson Greer revealed in an interview that before the weekend's developments, efforts to mitigate the conflict had been made, though they ultimately fell short. This trade war has significant implications for businesses and consumers on both sides of the border. Meanwhile, the IndyCar Grand Prix serves as a diversionary event with President Trump attending, shifting attention away from the economic strife.
