Meta CEO Mark Zuckerberg was caught on a hot mic admitting to Donald Trump that he had no idea how to answer a question while sitting next to the president at a White House event.

Zuckerberg was among the moguls in attendance for a dinner on Thursday, alongside Apple CEO Tim Cook, Microsoft founder Bill Gates, the founder and CEO of Google, Sergey Brin, and Sundar Pichai, and OpenAI founder Sam Altman.

Trump asked the Meta CEO and founder how much he was planning on spending in the US during the televised event.

'Oh gosh, um, I think it's probably gonna be, something like, I don't know, at least $600 billion through '28, in the US, yeah,' he responded.

Trump noted that it was a lot of money, and Zuckerberg confessed, 'Yeah, no it's significant'.
