"Violence of any kind has no place in our civil discourse and we urge supporters on all sides to be civil to one another as tensions rise heading toward this very important election," reads a statement from Paul's camp, which called the incident "incredibly unfortunate."
"We are relieved to hear that the woman in question was not injured," the statement reads.
Mark Riddle, senior adviser to the Conway camp, told Huffington Post, ""Everyone is hoping she is okay and I don't think anybody believes this sort of behavior is tolerable."
"We can disagree on issues and be passionate about them but I don't think there is any room for someone throwing a young lady to the ground and stomping her on the head no matter how much they disagree with her," he said.
As you can see from the below video, shot at a different angle from the original footage, the victim's head gets pressed against the pavement as the boot comes down on her head, neck and shoulder. Photos at this website show that one of the men holding Lauren Valle down was wearing a "Don't Tread On Me" button.
Police in Kentucky have not identified the perpetrator. We've reached out to the victim for comment and will bring it to you if and when we get it.
Late update: MoveOn is urging Rand Paul to condemn the attack, and is calling for arrests in the matter.
