Mark Cuban

Mark Cuban has long maintained his status as an independent. In fact, during this election cycle, Cuban has played both sides. After Donald Trump declared his initial candidacy last spring, Cuban called his fellow billionaire "probably the best thing to happen to politics in a long, long time."

That sentiment changed this summer, when Cuban endorsed Hillary Clinton and said of Trump, "Is there any bigger jagoff in the world than Donald Trump?"

For Monday night's presidential debate, the Clinton campaign gave Cuban a front-row seat to heckle Trump. And he took advantage of it.

During the debate, moderator Lester Holt pressed Trump to explain why he has not released his tax returns. Trump claimed he will release his tax returns after the audit is complete. Holt noted an ongoing audit does not disallow an individual from showing one's tax returns.

Clinton fired back: "First, maybe he's not as rich as he says he is; second, maybe he's not as charitable as he claims to be; third, we don't know all of his business dealings, but we have been told through investigative reporting that he owes about $650 million to Wall Street and foreign banks -- or maybe, he doesn't want the American people, all of you watching tonight, to know that he's paying nothing in federal taxes."

Clinton also noted the only time the public has seen Trump's tax returns was in the 1990s and that instance proved Trump paid no federal income tax.

"That makes me smart," Trump said.

Cuban waited patiently for his moment in the spin room. Then he tore into Trump's tax comments.

"I get audited every year my taxes are…it takes me 45 minutes just to sign all the different taxes that I have to spend," Cuban said. "And I tell my tax lawyers and everybody, do what the law recommends. But I'm not against paying taxes. And I'll give you a perfect example. When the Dallas Mavericks were building a new practice facility, which was just opening, I had the opportunity to go to Dallas and and play different cities against each other to get different rebates and everything. I didn't do it. A couple years ago we had some issues in Dallas, I just wrote a check to the general treasury. This year, after the shootings in Orlando, I had concerns about the LGBT community in Dallas. I just wrote a million dollar check to the city of Dallas to support a bunch of different programs. I'm, I'm the luckiest guy in the world. There's nobody who's been as blessed as me and my family, so far, knock on wood, is healthy, and at some point you have to recognize you have to give back. And you have to realize that this is a country that's been great to us. And you can't just take, take, take, take, take, take."

Cuban also criticized Trump saying, "He's like that friend you have that's easy to pick on and just says crazy things. He's been saying the exact same things for 30 years."

Cuban was apparently a sight to see in the spin room.

The Mavericks open the preseason Saturday against the Pelicans.
