Argument: General statements in support of Citizens United
Citizens United, the group filing the lawsuit said, "Today's U.S. Supreme Court decision allowing Citizens United to air its documentary films and advertisements is a tremendous victory, not only for Citizens United but for every American who desires to participate in the political process." During litigation Citizens United had support from the United States Chamber of Commerce and the National Rifle Association.
Heritage Foundation fellow Hans A. von Spakovsky, a former Republican member of the Federal Election Commission,said "The Supreme Court has restored a part of the First Amendment that had been unfortunately stolen by Congress and a previously wrongly-decided ruling of the court."
Joel Gora, a professor at Brooklyn Law School who had previously argued the case of Buckley v. Valeo on behalf of the American Civil Liberties Union, said that the decision represented "a great day for the First Amendment" writing that the Court had "dismantled the First Amendment 'caste system' in election speech."
