A Las Vegas immigration activist is alleging a member of Republican Senate candidate Rep. Joe Heck's staff assaulted her as she filmed him leaving an appearance. Viridiana Vidal filed a police report against Keith Hughes, accusing him of pushing and pulling her. Vidal says she received a bruise on her right leg. The alleged incident happened after Heck met with the group, Hispanics in Politics, in his capacity as a congressman. Vidal is a former Telemundo journalist who now works for the pro-immigration reform group, America's Voice. She was one of about 20 activists filming him and surrounding his vehicle.
