# US President Donald Trump, furious over a disparaging new tell-all book about him, threatened to sue authors and media outlets that use anonymous sources. Trump has made suing people an integral part of his brand as he made his way up from New York real estate mogul to the US presidency twice, and this time he is taking aim at the common practice of books and news stories using unnamed sources. Trump is also famously contemptuous of mainstream media in America, which he routinely labels the “fake news” media.
