A distorted video of House Speaker Nancy Pelosi caught fire on Facebook. Despite being fake, FB has declined to remove it. Now, FB has chosen to notify users who attempt to share the clip that it's faked. FB says people who see the video in feed, try to share it from feed or already shared it is alerted that it's false. A new menu pops up when a user taps a share button, notifying them that there has been new reporting on video.
