As early as Monday, the Supreme Court could decide to revisit its landmark Citizens United ruling of two and a half years ago.
That case gave corporations the green light to spend unlimited amounts in political campaigns. Now, a Montana case could lead the high court to take a second look at Citizens United.
Meanwhile, the role of Chief Justice John Roberts in the case is also raising questions in Congress.
Politicians have battled on Capitol Hill over the Citizens United decision ever since the Supreme Court’s ruling in January 2010. Days later, as President Obama delivered his State of the Union address, he scolded the Supreme Court justices who sat right below him.
