Government Watchdog Raises Questions Over Possible Supreme Court Conflict Of Interest

Common Cause, the government watchdog group, says Supreme Court Justices Antonin Scalia and Clarence Thomas had a conflict of interest in last year's landmark case that permitted corporations to directly fund campaign ads.

Common Cause is asking the Justice Department to investigate possible connections between the Justices and Charles and David Koch, the billionaires who have funded many conservative causes.

And the group says the Justice Department should ask the court to reconsider the case if it verifies that conflict of interest. We speak with Los Angeles Times reporter Tom Hamburger.
