Trump's fleeting tweets alarm archivists

President Donald Trump sent a number of tweets to the 23.5 million followers of his personal Twitter account. But they didn’t show up in the tweets of his official Twitter handle @POTUS — raising questions about whether those messages from the most powerful man on Earth will be archived for posterity. Because some of Trump's headline-grabbing, market-moving tweets might never become part of the presidential history books, archivists fear that Americans could be left with an incomplete record of how the United States was governed in the Trump era.
