Joe Biden said Donald Trump's plan to impose a 25% tariff on Mexican and Canadian imports is "counterproductive."

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.

Economists worry that Trump's tariff plan will raise the prices of a range of imported goods, from cars to electronics.
