Far-right firebrand Tomi Lahren caused laughter by questioning businessman Mark Cuban’s knowledge of international trade and taxes.

Cuban took to X, commenting on Trump’s recent rally in Michigan, where he claimed, “We’re going to bring back the car industry.”

According to The Detroit News, Trump said, “We’re not going to let it disappear. We’re going to bring back jobs, we’re going to bring back factories, and make Michigan very successful again. And we can do that very easily through the taxation of foreign nations.”

Cuban asked how Trump intends to tax another nation.

Lahren replied, “Do you not know what a tariff is?”

It’s similar to another question from a MAGA follower, in which Cuban explained how a tariff doesn’t tax foreign businesses but passes the cost on to consumers. Some have even predicted such a move would destroy the economy.

“A tariff is a tax imposed on foreign-made goods, paid by the IMPORTING BUSINESS (Walmart would be an example) to its home country’s government,” wrote Cuban. “(USA) As an example, Walmart imports billions and billions of goods. If there is a 10 percent tariff, Walmart pays the US government 10 percent on those billions, and guess who they pass that cost on to?”

Trump continues to promote the idea that high tariffs would help American jobs and pay down the deficit. According to experts, it would increase the prices of purchases, and there wouldn’t be any penalty to the country of origin.

The Libertarian Pary of Tennessee replied, telling Lahren, “That will make the price of cars skyrocket.”

Producer and filmmaker Esé Morrison asked, “Who pays a tariff Tomi? I’ll wait.”

Chuck Thomas from the Truth Barker podcast posted a laughing emoji saying, “Tomi, you don’t.”

Conservative author Tom Nichols also chimed in:

“Kind of a nice Death of Expertise moment: Youtuber asks globally known entrepreneur if he understands what a tariff is I’m gonna guess that yes, he does.”
