Meta CEO Mark Zuckerberg's hot mic moment during a dinner with President Donald Trump on Thursday was "quite a moment," according to one analyst.

Sara Fischer, media reporter for Axios, joined CNN's Kaitlan Collins on "The Source" to discuss the dinner, which was attended by business leaders like Zuckerberg, Apple CEO Tim Cook, and Microsoft CEO Satya Nadella. The press was invited to part of the dinner, and some business leaders gave thanks to Trump for his pro-business policies.

One reporter asked Zuckerberg what he thought about free speech issues in the United Kingdom. Zuckerberg seemed caught off guard by the question.

Zuckerberg, who was seated next to the president, leaned in toward Trump. A hot mic caught him saying, "I wasn't ready for our announcement. I wasn't sure what number you wanted to go with."

"I thought that was quite a moment," Collins said.

"Quite a moment," Fischer said. "These guys all thought the free speech and censorship that was such a big deal during the first administration was behind them, so I really do think Mark Zuckerberg was caught off guard there."

"As long as they can focus on AI and innovation, they won't have to worry about all that Republican heat against them for what was so-called censorship," she continued.
