A witness from the scene says a man was walking through the anti-reform group to get to the pro-reform side when he got into an altercation with the 65-year-old, who opposes health care reform.

The 65-year-old was apparently aggressive and hit the other man, who then retaliated by biting off his attacker’s pinky, according to Karoli from DrumsnWhistles.

The man took his finger and walked to Los Robles hospital for treatment.
