Trump is blaming Canada for wildfire smoke drifting into the US and threatening higher tariffs, a move that mostly hits Americans — bad for consumers and US-Canada relations.

• Trump says he'll add a "pollution cost" to Canadian tariffs over wildfire smoke choking 20 states, including some of the worst air in the world in Minneapolis.
• Since tariffs are paid by importers, this mainly raises costs for Americans, not Canada.
• A Canadian official pushed back, noting Canada sent crews and resources to help during US wildfires and hurricanes.
• Trump Media is reportedly pitching a $100,000-a-month fee for a fast feed of his posts, raising insider-trading concerns.
• Other US strains pile up: gas near $4, diesel at $5, a food-poisoning outbreak tied to Taco Bell lettuce, and ongoing US strikes on Iran hitting bridges and water plants.

Outlook: Expect more tariff threats and worsening US-Canada friction, with no real fix for the smoke or the cost-of-living squeeze.
