Anonymous targets lawmakers for defeat

"We are calling on voters, activists and keyboard warriors under all banners to unite as a single force to unseat the elected representatives who threaten our essential freedoms and who were so quick to minimize our individual constitutional rights for a quick corporate profit," the group wrote.

The campaign is a partnership between Anonymous and several Occupy Wall Street protest groups. 

Anonymous is most known for its attacks on websites. Last month, the group crashed the websites of the Justice Department, record labels and movie studios in retaliation for prosecutors shutting down file-sharing site Megaupload.

The group also hacked two websites of the Federal Trade Commission this month.
