On Tuesday, speaking to Extra’s Renee Bargh on the set of his hit ABC show Shark Tank, Mark Cuban ripped Donald Trump yet again, asserting that Trump was getting “stupider before your eyes,” adding, “He’d get kicked out of 'Shark Tank' so fast, it would make your head spin.”

Bargh began by asking Cuban what he currently thought of Trump. Cuban replied: “You know what? It’s rare that you see someone get stupider before your eyes, but he’s really working at it … And so you have to give him credit. It’s not an easy thing to do, but he’s accomplished it.”

Bargh pointed out, “He says he’ll make a good president because he’s strong in business and a great negotiator.”

Cuban, who is a billionaire himself and the owner of the Dallas Mavericks, laughed that off, saying bluntly, “Well, let’s look at it this way: Name one good deal he’s done.”

Bargh responded, “I can’t.”

Cuban continued:

Neither can he. When he talks about his great renegotiations, they’re renegotiations, so tell me if you think this is a good deal: I lose four casinos, they go out of business, but I’m really good at renegotiating the debt of my companies that have already gone out of business He’d get kicked out of Shark Tank so fast, it would make your head spin.

Bargh asked him if he had communicated recently with Trump, prompting Cuban to answer:

He sent me an email when I started picking on him. What happened was I really didn’t like Ted Cruz, so I started helping Donald, tried encouraging him, 'cause I thought he’d be, and to this day thought he’d be a better candidate than Ted Cruz… But at some point, you’ve got to start learning and understanding the issues, you know? Donald has been in this a year but you don’t look at him and say, “Wow, he’s gotten so much smarter on this topic or that topic.” In fact, you look at him and say, “What the hell are you talking about?” That’s not good for America.”

Earlier in the day, after the revelations from a Federal Election Commission report showing Trump only had $1.3 million in cash on hand compared to Hillary Clinton’s $42 million at the beginning of June, Cuban called out Trump for bluffing about his real worth, tweeting:

Cuban followed with a series of retweets from June 8 that were amusing predictions of Trump’s future behavior:

Cuban had ripped Trump back in early May, saying, “There’s that guy who’ll walk into a bar and say anything to get laid. That’s Donald Trump right now to a T. But it’s all of us who are going to get f***ed.”

Last December Cuban wrote in a blog post: "Donald can talk for hours and say nothing of true substance. But every few sentences he is going to spout out Headline Porn that is going to fit in 140 characters or so and unquestionably have to be discussed by 'The Political Shows.'”
