George Clooney denies unloading on MSNBC producer after Brzezinski claim about actor's op-ed critical of Biden

"That never happened. Now, it's an interesting thing. You know, here's a funny thing about this. You're writing a book, you know, and all I have to do is tell the truth. I have emails. I was ticked off when it was Mika Brzezinski - who I like, perfectly nice woman - but she said that, you know, that President Obama was behind me writing the op-ed, and that's not true at all. It has no basis in fact. And I wrote Mike Barnicle and I just said, what is that about?" he told CNN's Jake Tapper.

Author Chris Whipple wrote in his new book, "Uncharted: How Trump Beat Biden, Harris, and the Odds in the Wildest Campaign in History," that the "Morning Joe" segment led to Clooney reportedly calling a producer and shouting, "How the f--- could you let her link me with Barack Obama saying he made me write the op-ed?" 

Clooney said Barnicle, who appears on "Morning Joe" often, said he had no idea. 

"And I said, the one thing you know about me is that I don't take my marching orders from anybody. And that's the only person I know over there. And I wrote him. We have a four-email exchange," Clooney added. 

"And then this guy [Whipple] says, I called up a producer, who, I don't know how to call a producer there. I don't know any producer there. And I yelled at them, which isn't true. And here's the problem with that, what that does is it calls into question any other facts in this book," Clooney told Tapper. 

Tapper also asked Clooney if he thought the Democratic Party should have had some kind of primary after Biden dropped out.

"Yeah, if you think about it, and she may have ended up winning that contest," he said, referring to former Vice President Kamala Harris. "And here's the problem that we were facing with that. Whether or not you agree that that administration was successful or not, that's a different thing. But the perception was, and how they were running was, that it was a failed administration. I could argue that it's not, but that's a different argument."

Clooney continued, "You can't run against yourself, right? And that's why that was a difficult campaign. It's hard to run against yourself and say, well, yeah, I disagree with all this stuff."

He said it was impossible for Harris because she would have had to "run down" Biden.

"I'm a Democrat in Kentucky, so I get it. When I saw people on my side of the street not telling the truth, I thought that was time," he said.
