The first known video footage of a Supreme Court hearing was posted on YouTube.
The video appears to show footage from a campaign finance case in October 2013 as well as a spectator disrupting an oral argument on Wednesday. A group called 99Rise claims credit for the disruption.
Court spokeswoman Kathleen Arberg says officials are reviewing the video and screening procedures.
No cameras are allowed in the courtroom. Reporters and spectators are required to leave electronic devices behind before court sessions.
