"From September 23-26, tens of thousands of anti-war and global justice activists will flock to Washington, DC for the largest mobilization since last year's RNC protests. SeptemberAction.org will serve as an information clearinghouse for that weekend. Read our call to action.
On this website you can find or post local and national groups participating in the mobilization, a calendar of events, legal information, posters, materials, and housing and transportation resources."
