Trump said in a post to Truth Social on Monday that one of his first executive orders would be to hit Mexico and Canada with a blanket 25% tariff. Mexico and Canada are the second and third top suppliers of goods to the U.S., according to the Office of the U.S. Trade Representative. The U.S. imports the most goods from China.

Donald Trump’s threat of 25% tariffs on Mexico and Canada would cost the US economy as many as 400,000 jobs and increase prices for American consumers, according to the Mexican government.
