Mark Cuban criticized Donald Trump’s tariff proposals at a rally in La Crosse, Wisconsin, suggesting that Trump doesn’t fully understand how tariffs work.

Cuban pointed out that Trump mistakenly believes that China would bear the cost of increased tariffs on imports, likening it to Trump’s past claim that Mexico would pay for the border wall.

Cuban emphasized that U.S. importers, not foreign countries, pay tariffs, and warned that such policies could significantly raise costs for American households.

He reiterated his opposition to Trump’s plans, calling them inflationary and detrimental to American consumers, CNBC has reported.

Cuban is campaigning in support of Democratic nominee Kamala Harris, visiting multiple swing states to promote her economic agenda, while Trump is receiving support from billionaire Elon Musk, who is actively campaigning for him in Pennsylvania.
