For the First Time in History Video of the Supreme Court Secretly Recorded

(CNN) — In an apparent first at the tradition-minded Supreme Court, an advocacy group surreptitiously recorded video of an oral argument that was interrupted by a spectator.

The group 99Rise.org, which supports campaign finance reform, posted the video of Wednesday’s proceedings on YouTube as part of a protest over the issue.No electronic devices, or still or video cameras are permitted in the court’s public sessions.
