Mark Cuban Calls Trump the ‘Zoolander President.’ He’s Also Not Ruling Out a White House Bid

March 13, 2017, 6:00 AM UTC

Billionaire entrepreneur Mark Cuban has said he won’t rule out a future presidential run.

Speaking on a panel at the South by Southwest Festival in Austin, Texas, Cuban told audience members he “wouldn’t say never” when it comes to a potential White House bid, CNBC reports.

While the Dallas Mavericks owner and Shark Tank star investor said he supported some of President Donald Trump’s economic policies, he described Trump as “the Zoolander president,” referencing Ben Stiller’s narcissistic and dim-witted character in the movie of the same name. Cuban also mocked Trump’s apparent lack of knowledge when it comes to emails and using online search engines.

Cuban, who identifies as a libertarian, also said that he strongly opposes Trump’s socially conservative policies and added that he could do a better job than Trump in the Oval Office.

Despite initially supported Trump’s candidacy in 2015 and declaring he would consider serving as his vice president, Cuban later became one of his most outspoken critics, calling the Republican a “superstar liar” and an “immediate danger” to national security.

Cuban told the audience in Austin that this switch occurred after he “got to know” Trump personally.
