This act was first proposed by the senator Charles Summer in 1970, who also created the first draft in subsequent years. However, this was only approved in 1975 and Summer did not live to witness it. Additionally, the act was supported and sponsored by others including the senator Benjamin Butler, who also worked against organizations such as the Ku Klux Klan. Thus, these two senators were closely associated with this act.
