From the excellent Hatewatch blog @ the Southern Poverty Law Center:

A group that monitors hate groups says it sees links between the San Diego Minutemen and white supremacists. The local Minutemen reject any suggestion they are racist. KPBS News Director Michael Marcotte has the story.

In one of his frequent on-line posts to the San Diego Minutemen, Ray Carney revealed he worked as a computer expert for the White Aryan Resistance for eleven years.
