Sen. Dick Durbin (D-Ill.) has called for the Supreme Court and Chief Justice John Roberts to adopt a binding code of conduct in response to a ProPublica story that revealed Dallas real estate billionaire Harlan Crow had paid tuition for Supreme Court Justice Clarence Thomas’ grandnephew. Durbin argued that the revelations demonstrate the need for a binding code of conduct, and his call for action has been echoed by other lawmakers. The Supreme Court currently has a code of conduct, but it is not binding.
