Donald Trump sat down with Tucker Carlson Tuesday evening for an exclusive, wide-ranging interview on his historic indictment, the state of the world under President Joe Biden and the 2024 presidential contest.

Trump told Carlson that he doesn’t believe Biden will be the Democratic nominee in 2024, saying there is “something wrong” with Biden mentally.

“Look, I watch him just like you do. And I think it’s almost inappropriate for me to say it. I don’t see how it’s possible," Trump said.

“Something wrong”

Trump cited Biden’s garbled response to a question from weatherman Al Roker on whether he is running. Biden said he "plans" to do so but his response quickly went off the rails, as Trump noted.

“There’s something wrong, Trump said. "I saw his answer today on television about whether or not he was going to run to a very nice guy named Al Roker. You can’t get a softer question than that. That was a long answer talking about the eggs and this and that. Look, I don’t think he can.”

Bernie Sanders is “100 percent sharp” despite being older than 80-year-old Biden, Trump said, adding Biden's problem is "not an age thing."

“I just don’t see Biden doing it from a physical or a mental standpoint," he said.

Trump's warning

Trump also spoke at length about global affairs, his relationships with world leaders like China's Xi Jinping, and the threat of nuclear war. Ukraine is getting "obliterated" in its war with Russia, but the Biden administration doesn't seem interested in de-escalation, Trump said.

“The world is exploding around us. You could end up in a third World War," he said.

Meanwhile, Biden is not equipped to deal with the likes of Xi, Trump warned, saying the Chinese leader is "brilliant."

“They’re all top of the line. Our guy’s not top of the line. Never was. These are top of the line people at the top of their game," Trump said.

Trump defiant

Biden, although weak, is surrounded by “vicious” radicals who pose a greater threat to America than Russia or China, Trump said.

“The biggest problem is from within. It’s these sick, radical people from within,” he argued.

Trump also discussed the weaponization of the legal system and his historic indictment in Manhattan over “hush money." The Republican 2024 frontrunner said his enemies are using “the old Soviet process” to hamstring him, but he will not be pressured into dropping out.

“I’d never drop out. It’s not my thing, I wouldn’t do it”, he insisted.
