Mark Cuban's Dispute With Donald Trump Adviser Enters Fifth Day

Political aide Stephen Miller, an advisor to Donald Trump, has faced criticism from billionaire investor and TV personality Mark Cuban.

The ongoing feud between Cuban, a prominent "Shark" on the TV show *Shark Tank*, and Miller began on September 4, centering on their differing views about trade tariffs and American economic policies ahead of the November presidential election. Cuban has long been critical of Trump, having endorsed Hillary Clinton in 2016 and subsequently supported Joe Biden in 2020 and Kamala Harris for the 2024 election.

The conflict started when Cuban criticized Trump's economic policies on the social media platform X (formerly Twitter). He argued against the former president’s proposed punitive tariffs, stating, "There is a huge difference between targeted tariffs and across-the-board tariffs. Across-the-board tariffs are a tax on everyone. They make no sense at all."

Cuban also praised Harris for her approach to business, claiming she is more supportive of domestic industries. Miller responded on September 5 by accusing Cuban of representing the interests of "billionaire elites" who benefit from offshoring. He claimed Trump’s economic plan focuses on American labor, while Harris’s plan enriches foreign workers and nations.

Cuban countered Miller's claims, correcting his spelling and highlighting his efforts to move production back to the U.S. He mentioned investing in Guardian Bikes and Cost Plus Drugs, which relocated manufacturing to Indiana and Dallas, respectively. Cuban also pointed out his involvement in the movie *The China Hustle* and his criticism of Chinese IPOs.

Miller continued to challenge Cuban, questioning how many of his Shark Tank companies had moved manufacturing overseas. Cuban replied that none had, and he mentioned his investment in Wecultivate.us, a platform that helps consumers identify U.S.-made products.

Cuban then asked if Trump’s products are made in the U.S., but Miller did not address this query. Instead, the debate intensified, with Cuban accusing Miller of dishonesty about investment practices and the impact of tariffs. Cuban also apologized for a previous post that he later deleted.

Cuban explained that his experience with tariffs was costly, affecting both the price of imported parts and the company’s margins. He argued that the effect of tariffs is more complex than Miller’s oversimplified view.

Miller has yet to respond to Cuban’s latest points, leaving the resolution of their dispute uncertain.
