WASHINGTON, DC - JANUARY 21: Attendees hold signs as they listen to speakers during a rally calling for an end to corporate money in politics and to mark the fifth anniversary of the Supreme Court's Citizens United decision, at Lafayette Square near the White House, January 21, 2015 in Washington, DC. Wednesday is the fifth anniversary of the landmark ruling, which paved the way for additional campaign money from corporations, unions and other interests and prevented the government from setting limits on corporate political spending.
