Step-by-step explanation:
In the case of Citizens United v. Federal Election Commission, the Supreme Court ruled in a 5-4 decision that the restrictions imposed by the Bipartisan Campaign Reform Act (BCRA) and enforced by the FEC violated the corporation's First Amendment right to free expression. The BCRA prohibited campaign communications close to an election and required donors to be disclosed. The Supreme Court concluded that these restrictions on corporate spending during election cycles violated the First Amendment.
