Fake news galvanized US president-elect Donald Trump's supporters, and sullied his enemies. Now it may be Elon Musk's turn. Quartz adds: The CEO of Tesla and SpaceX has his fair share of detractors, but a new era in a public relations battle to discredit him appears to be taking shape. Bloomberg reports that hard-right groups are lining up to back misleading websites and fake journalists who attack Musk's business empire. Many of the attacks on Musk begin with something factual: His businesses were built, legally, with the help of billions in government contracts and incentives for renewable energy and space transport. But they go on to accuse Musk of fraud and wasting taxpayer dollars; some compare him to a convicted felon. At least three conservative sites have run negative pieces about Musk -- by a nonexistent writer named "Shepard Stewart" -- that include "Elon Musk Continues to Blow Up Taxpayer Money With Falcon 9" and "Elon Musk: Faux Free Marketeer and National Disgrace." Two later retracted the stories. "There's a very obvious precedent" for this, says Sam Jaffe, managing director of Cairn Energy Research Advisors. "That's Hillary Clinton." Musk tweeted this week, "Can anyone uncover who is really writing these fake pieces?"
