Former President Donald Trump writes in a new book set to be published next week that Mark Zuckerberg plotted against him during the 2020 election and said the Meta chief executive would “spend the rest of his life in prison” if he did it again.

It represents Trump’s most recent attack on Zuckerberg, who he has repeatedly accused of intervening in the last presidential election. And it comes as Meta has taken steps to assure conservatives it will not influence this year’s campaign.
