Zuckerberg caught on hot mic telling Trump 'I wasn't sure' how much to promise to spend on AI in the US

Here is a 197-word summary of the news article: The article discusses a recent interaction between Meta CEO Mark Zuckerberg and former President Donald Trump at a White House dinner with tech executives. During the event, Trump asked Zuckerberg how much Meta planned to spend on AI in the US, to which Zuckerberg responded at least $600 billion through 2028. However, a hot mic moment later captured Zuckerberg telling Trump that he "wasn't sure what number [Trump] wanted to go with." This interaction highlights the evolution of Zuckerberg's relationship with Trump. A year ago, Trump had threatened Zuckerberg with imprisonment, but the two have since patched things up. Zuckerberg has made efforts to curry favor with Trump, including donating $1 million to his inauguration, changing Meta's policies, and adding a pro-Trump booster to the board. In a subsequent statement, Zuckerberg acknowledged that Meta may invest even more than the $600 billion figure he initially provided, and that he had simply shared the lower number through 2028 before clarifying with Trump afterwards. The article suggests this interaction reflects how Zuckerberg's efforts to appease Trump have been paying off.
