evidence: Tafari Campbell, a Barack Obama employee who formerly worked as a chef in his White House, was found dead in a pond near the ex-president's home on Martha's Vineyard, Massachusetts, on Monday. [...] The Obamas paid tribute to Campbell in a statement following his death: "Tafari was a beloved part of our family. When we first met him, he was a talented sous chef at the White House—creative and passionate about food, and its ability to bring people together. In the years that followed, we got to know him as a warm, fun, extraordinarily kind person who made all of our lives a little brighter." After Campbell's death was confirmed, a wave of conspiracy theories hit social media. A number of prominent right-wing Twitter accounts have questioned the authorities' version of events, despite failing to provide notable evidence to the contrary.
