IndyCar races toward Washington D.C.'s National Mall at nearly 200 mph this weekend as Trump celebrates America's 250th birthday. Meanwhile, Canada suspends trade talks, triggering 50% tariffs on imports, and the U.S. national debt hits $40 trillion—doubling in less than a decade. The IndyCar Grand Prix route changed from congressional land to the National Mall after political intervention; Trump will wave the green flag and take a lap in his own car on Sunday.
