Teresa Heinz Kerry's favorite charity has also funded The Ruckus Society, an anarchist group known for disrupting the World Trade Organization meeting in Seattle in 1999 and planning similar disruptions for the New York convention. The group has been training protesters for the GOP convention in the art of sit-ins and blockades.
It is mentioned further down in the article.
