(Chicago, IL) -- Bruce Rauner's campaign is up in arms, claiming Governor Quinn's security team verbally assaulted a Rauner videographer at a bill signing yesterday. A spokesman says the videographer was on public property and had a right to attend the event. But, Quinn's people weren't having it. A video of the incident shows a security guard yelling at the young videographer, telling him to get on the other side of the sign and stay out. Quinn's team says the Rauner plants have become more aggressive at events lately and have become a security issue.
