evidence: Tafari Campbell’s widow didn’t expose the Obama family, contrary to social media claims [...] This video offers no evidence that the wife of the late Tafari Campbell, personal chef to the Obama family, "exposed" the Obama family in any way or blamed them for her husband’s death. We also found no evidence to support the claim. [...] Rather than elaborating on the allegation that Campbell’s widow recently exposed the Obama family, the video’s narrator delves into an old debunked claim that the late comedian, Joan Rivers, was killed after she made comments about former President Barack Obama’s sexuality and former first lady Michelle Obama’s gender identity.
