Obama political arm goes on offense

"The same angry groups and right wing extremists we saw at rallies during last year's election are at it again," Mitch Stewart, director of Organizing for America, says in a nearly two-minute long video that will be emailed Friday afternoon to Obama supporters.

"They are spreading lies about the president's plan and with the encouragement of Republican leaders, and funding from their special interest allies they are disrupting pubic events. They are trying to drown out public discourse and legitimate conversation on this issue in communities all across America."

The video shows Stewart sitting in an office and cuts to images of protesters disrupting town halls. Stewart goes on to instruct supporters to visit a Web site to "sign up for events in your community and contact your representatives."

At the conclusion of the 2008 election, Obama transitioned his presidential campaign into OFA, which is now a project of the Democratic National Committee.
