Donald Trump is increasingly convinced that Mark Zuckerberg was responsible for the 2020 outcome, according to three people familiar with the matter. Trump's growing antipathy toward Zuckerberg helps illuminate the former president's position on the video-sharing app TikTok.

Trump tried to ban TikTok while he was in office before a court blocked the attempt near the end of his presidency. Trump spokesman Steven Cheung said Trump views Chinese ownership of TikTok as a threat to national security but appreciates that millions of people like the app.
