I heard O'Neill on a local radio station and he was asked if the Swiftvets are a 527. He stated no they were not, something about small donors and can't remember what he termed them but not 527.
Swift Boat Veterans for Truth is a tax exempt non-partisan public advocacy "527" organization that consists of and is limited to former military officers and enlisted men who served in Vietnam on U.S. Navy "Swift Boats" or in affiliated commands.
