Trump Threatens Tariffs on Canada Over Wildfire Smoke

President Donald Trump said Friday in a social media post that Canada is failing to manage its wildfire response, as smoke from the blazes has blanketed major U.S. cities including New York and Chicago. He threatened to impose tariffs on Canada in response, though he did not provide details on how such a policy would work or when it might take effect. Canadian officials have not yet commented on the threat.
