Ugh, a couple of anti-vaxxers harassed me in front of my house and goaded me into discussing RFKJr. Of course I looked my Sunday best in our brutal heat wave. What about the people? Well, at least Houstonians now know that I support the team…#GoTexans pic.twitter.com/d0NIgNElKN

Cuban, owner of the Dallas Mavericks basketball team and investor in the television show shark tankgot into the discussion Sunday while responding to one of Rogan’s tweets about Hotez.
In the tweet, Rogan defended the need for a debate and referred to people in the medical industry as “heartless monsters.” She said those in the medical field “see human beings as an opportunity to generate insane wealth regardless of the tragic consequences.”
Cuban, who in 2022 founded the online generic drug company Mark Cuban Cost Plus Drug Company (MCCPDC), attacked Rogan’s criticism of the healthcare industry. The investor said the podcaster’s comments were “disrespectful” to the nation’s medical professionals. Cuban also criticized Rogan and Kennedy Jr. for trying to force Hotez into a debate with Kennedy Jr.
“Trying to intimidate Dr. Hotez is ridiculous. You have producers that will prepare you and you can control the conversation,” Cuban said in the tweet. “@RobertKennedyJr He also has a staff ready to prepare him, and these topics are the ones he talks about in every speech. They both do this daily. Dr. Hotez works every day to try to find ways to help people.”
Way of speaking in generalities Joe. I’m not saying there isn’t a lot of screwed up about the pharmaceutical industry. That’s why we created https://t.co/jYSNkP7amr. But to ignore that the same industry has saved who knows how many lives is bullshit and you know it.
It’s also disrespectful to everyone… https://t.co/bUawoBgbH6—Mark Cubano (@mcuban) June 18, 2023
Cuban said news week that Rogan, Kennedy Jr. and Musk were “harassing” Hotez, so he felt the need to step in and say something on his Twitter account, which has nearly 9 million followers.
“I thought it was unfair that Joe, Kennedy and Elon were effectively intimidating Dr. Hotez, so I decided to say so,” Cuban said in an email to news week. “Elon and Joe have worked hard to create their respective platforms and they have the right to use them however they want. But I felt like I could also use my platform to say how I felt.”
Hotez said during a Sunday night appearance on MSNBC that anti-vaccine misinformation is a “deadly force” in the US. He said during the interview with Mehdi Hasan that he is happy to be on Rogan’s podcast and talk about vaccines and share information. However, he did not say if he would debate Kennedy Jr.
“I offered to follow Joe Rogan, but not make it into the Jerry Springer show with RFK Jr.”, he said.
