'Hey tough guy': Mark Cuban goes to war with MAGA-loving Fox News host

Business giant Mark Cuban faced off with one of Donald Trump's top defenders in the media on Friday.

It all started when Cuban reportedly "slammed fellow billionaire Elon Musk and other business figures who have recently signaled support for former President Trump's campaign in a social media post."

Fox News weekend host Mark R. Levin, who was recently mocked online for lamenting a lack of billionaires offering to help Trump post bond in his case, is frequently promoted by Trump on the ex-president's social network, dubbed "Truth Social." Levin noted the report about Cuban, and shared it on social media with some rather angry commentary.

"Mark Cuban is an overrated a--hole who lucked out early in his business career," Levin wrote. "Why doesn’t he move to California from Texas?"

The media personality continued on Friday, "You’re welcome to come on my show to debate anytime, tough guy. But your obsessive jealousy of Elon Musk is obvious."

But Cuban didn't take that sitting down, instead recommending Levin do some conservative reading.

"Hey tough guy lol. You should read some Ayn Rand," Cuban wrote in response. "Here is a starter book for you to try."

Cuban recommended to Levin Rand's book, "The Virtue of Selfishness."
