Billionaire investor and Dallas Mavericks owner Mark Cuban had some words of caution about GOP candidate Ted Cruz in an interview with WABC on Tuesday.

Speaking on the Rita Cosby Show, Cuban talked in depth about the GOP candidate field. The Texas senator, he said, reminds him of a reincarnation of infamous Joe McCarthy, a Wisconsin senator made famous for communist witch hunts during the Cold War.

"I think he is Joe McCarthy reincarnate. You know, he applies, he lives, he assigns labels to himself and he tries to live up to those labels," Cuban said. "He assigns labels the others, you know, and denigrates people who don't, who aren't pure in how they are. I just, you know, I keep on waiting for him to say something to the effect, you know, are you or have you ever been a member of some party?"

Cuban said he believes Cruz, who has led efforts to shut down the government over disagreements with President Barack Obama in the past, is an obstructionist and not constructive.

"I just think that he doesn't, he's not the type of person who will accomplish anything," Cuban said. "He's just obstructionist and he really, you know and Paul Ryan says it best, you know, that the Republican Party needs to go from being obstructionist, to get, to be one of propositions rather than opposition. And Ted Cruz embodies pure opposition without proposition."

He also voiced concerns about Cruz's ability to get anything done, if elected.

"Where he's been able to say, you know what, I was able to get this done," he said. "I was able to get people to vote with me and for me, and we were able to accomplish A, B and C. That's just a blank slate. And then when you talk to his peers, you get to see that they won't support him."

Cuban also said he suspects Cruz's rival, Donald Trump, is trying to stay in the limelight more than he is sincere about some of his extreme rhetoric.

"I think, you know Donald has got a side, where he's not all that self-aware, but he's self-aware enough that he doesn't want to go down in history as the worst, the worst president ever, or he wouldn't want to go down in history as the worst president ever," he said. "So I think, I think he'd adjust to the circumstances. So I don't think all of his being bombastic and all the screaming and all the rhetoric, I don't think he'd live up to all that."
