An unidentified protester threw what appeared to be a roll of papers at former Secretary of State Hillary Clinton on Thursday.
The unexpected moment, was caught on camera as Clinton spoke at the ISRI Convention in Las Vegas, the world's largest recycling industry convention and trade show.
Clinton was the keynote speaker at the event.
Not a stranger to controversy, the former first lady brushed off the incident, while security escorted the demonstrator out of the building.
Still no word on the protester's identity.
