NEW: The FBI says the woman behind Trump during his PA rally is *not* FBI assistant director Janeen DiGuiseppi after online users started spreading the bogus theory. Blurry video footage went viral where online users claimed the woman in the video was DiGuiseppi. Despite not even being able to see her full face, online users claimed with no evidence that the woman was the Assistant Director of the FBI's Insider Threat Office. "The allegations circulating on social media about an FBI executive and the rally in Butler, Pennsylvania are categorically false," an FBI spokesman said to the Daily Mail.
