In the years since the Supreme Court's 2010 Citizens United decision, political spending has skyrocketed, much of it in secret. The ruling has kept the media and public from knowing where this "dark money" comes from and what conflicts of interest exist. However, if President Obama decides to issue an executive order requiring contractors to disclose their political donations, as he is reportedly considering doing, journalists will soon be able to expose the hidden relationships between contractors and elected officials. Citizens United opened the financial floodgates to dark money groups - organizations that raise unlimited money from donors to pay for political advertising and campaign organizing but are not obligated to disclose where the money came from.
