Mark Cuban pours cold water on the idea that Donald Trump is a “great businessman.”

Billionaire Mark Cuban was cold-hearted about the idea that former President Donald Trump is a “great businessman” in an interview on CNN on Friday.

Cuban, an entrepreneur and ABC's Shark tank The television star has supported Vice President Kamala Harris in interviews and on social media since she won the mandate from President Joe Biden and was quick to support the Democratic Party's nomination this summer after Biden withdrew from the race. While Cuban said he was initially a fan of Trump's candidacy when he first announced his intentions in 2015, he is now completely annoyed with the former president. Cuban says Harris is the pro-business candidate who can best serve the interests of small businesses and the economy as a whole.

On Friday, Cuban was asked by CNN anchor Kaitlan Collins whether he would invest in Trump's campaign efforts if he appeared Shark tankdetailing some of the former president's ventures into selling Trump-branded shoes, coins, cryptocurrencies, Bibles and pieces of his suit.

Cuban replied: “No, he is desperate. You only sell these things because you have to, because you need the money. People think he is a great businessman. If the job of the presidency was to invest in real estate, choose curtains and furnishings, then he would say “I'm probably not the best. He is not a businessman. And the worst thing about his business career is how often he harasses hard-working Americans.”

Newsweek The Trump-Harris campaign emailed for comment.

Cuban's comments come after Trump's business dealings came under recent scrutiny. In a lawsuit filed by New York Attorney General Letitia James, Judge Arthur Engoron ruled in February that Trump, his adult sons Donald Jr. and Eric, and the Trump Organization were liable for a scheme to harm the value of Trump's net worth and assets were illegally increased in order to achieve more favorable business deals. Trump has protested his innocence. Since then, the judge has ordered him and others to pay more than $350 million in penalties – a sum that, with interest, has risen to more than $489 million.

Engoron also banned Trump from holding any directorships for three years and his companies were banned from borrowing from financial institutions. The former president is currently appealing the ruling, and some New York appeals court judges have indicated they may overturn the decision.

Meanwhile, in recent months, Cuban has readily enlisted Trump supporters and fellow billionaire Elon Musk to defend Harris against their attacks. Musk, the CEO of Tesla, founder of SpaceX and owner of

Cuban has told it before Newsweek that he viewed Trump's first term as “bad” and warned that a second term would be “worse.” He also views Harris as someone who will work with Republicans and independents.

“She’s not an ideologue,” he said, describing her as “far more stable” and “open-minded.” Cuban, in particular, believes Harris' economic policies are good for the country, saying they will benefit both ordinary Americans and small businesses.
