When a protester was yanked by his collar at a Trump rally, the incident was caught on camera and seemed to implicate Corey Lewandowski—Trump's campaign manager, who has already been accused of assaulting a female journalist. Naturally, the Trump campaign rushed to defend Lewandowski from a second accusation of violence on the job (among other allegations that concern even Trump staffers), and blamed it on the man next to him in a dark pullover. That man has since been revealed to be a security staffer for the Trump campaign.
Trump himself said that the incident was primarily the protester's fault for having a "horrendous" sign with profanity on it, and that although he gave Lewandowski credit for having "spirit," he didn't touch him. A Trump spokesperson, Hope Hicks, declined to say why Trump's campaign manager was interacting with protesters, although Trump blamed it on lax policing in an interview with ABC (below). Just to be clear, this was separate from the other, much more violent incident at the same rally in Arizona:
Ms. Hicks directly blamed the incident on the man in the pullover in a statement Saturday night. She suggested, according to Politico, that "his actions were justified by the behavior of the protester, who can be seen in the video grabbing the arm of a young woman in front of him."
What she did not suggest, or in any way identify, was that the man is a security staffer for the Trump campaign. It was not a case of poor internal communication or mistaken identity, however—she did know. She said as much when confronted by reporters on Sunday, telling Politico, "Although we did not identify this individual, we did not make any suggestion as to his affiliation or lack thereof."
Translation: "Yeah, we pretended he was some random guy, but we didn't say he wasn't our hired muscle. So, technically, we didn't lie."
