According to this:

All told, there were four attacks on our people [Recall Gray Davis supporters]... Our supporters were kicked, punched, beaten and tackled. There were several men attacked, a 20-year-old woman and then the "WAR" [Workers Against the Recall] thugs chased after and harassed, screamed at and terrorized a 7-year-old boy who was crying and shaking after watching his mother and father assaulted.

The link includes several still photos and video from Fox News. In the video, you can the end of the attacks, and it's a bit more than just a minor scuffle.

Note also that the WAR meeting was sponsored by the State Building and Construction Trades Council. They're a private agency, however, recall supporters have claimed that some tax money might have been improperly used by Davis to fight the recall.
