A year ago, the Supreme Court decided on one of the most controversial campaign finance cases in recent history: Citizens United. The Court ruled 5-4 in favor of lifting a ban on corporate spending on political campaigns. Justice Scalia and Justice Thomas were two of the judges who concurred with the opinion of the court. Now, a liberal group, Common Cause, has filed a petition arguing that Scalia and Thomas should be taken off campaign finance cases.
The group says the two Justices have ties with conservative financier, Charles Koch, a major funder of conservative causes. Law professor Jeffrey Rosen explains the accusations against Scalia and Thomas and whether they should recuse themselves from future campaign finance cases.
