The U.S. Supreme Court creates an exemption to advertisement restrictions set out in the 2002 McCain-Feingold campaign finance law. In Federal Election Commission v. Wisconsin Right to Life, Chief Justice John G. Roberts Jr. writes that only ads that make specific appeals to vote for or against a candidate can be prohibited in the period covered by the law – 30 days before a primary election and 60 days before a general election. The Court says limits on TV ads sponsored by corporations or unions in that period amount to censorship of political speech, which is protected under the First Amendment.
