For a short time Thursday evening, Twitter appeared to lose one of its most avid users: The page for the @realDonaldTrump account displayed an error message. Twitter's standard error message, "Sorry, that page doesn't exist!" appeared in place of President Donald Trump's personal Twitter feed. A short time later, the account page reappeared and seemed to be functioning as normal. According to NBC News, the White House had no immediate comment. In May 2009, Trump, then a private businessman, sent his first tweet promoting a forthcoming appearance on the Late Show with David Letterman, the BBC reported.
